+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+ -export-symbols SYMFILE
+ try to export only the symbols listed in SYMFILE
+ -export-symbols-regex REGEX
+ try to export only the symbols matching REGEX
+ -LLIBDIR search LIBDIR for required installed libraries
+ -lNAME OUTPUT-FILE requires the installed library libNAME
+ -module build a library that can dlopened
+ -no-fast-install disable the fast-install mode
+ -no-install link a not-installable executable
+ -no-undefined declare that a library does not refer to external symbols
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -objectlist FILE Use a list of object files found in FILE to specify objects
+ -precious-files-regex REGEX
+ don't remove output files matching REGEX
+ -release RELEASE specify package release information
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR
+ -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
+ -shared only do dynamic linking of libtool libraries
+ -shrext SUFFIX override the standard shared library file extension
+ -static do not do any dynamic linking of uninstalled libtool libraries
+ -static-libtool-libs
+ do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]

+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
+ --mandir=DIR man documentation [DATAROOTDIR/man]
+ --docdir=DIR documentation root [DATAROOTDIR/doc/zfs]
+ --htmldir=DIR html documentation [DOCDIR]

+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.NOEXPORT:
* `mount-zfs.sh`: Run later in initramfs boot process after udev has settled
to mount the root dataset.
+* `export-zfs.sh`: Run on shutdown after dracut has restored the initramfs
+and pivoted to it, allowing for a clean unmount and export of the ZFS root.
+
`module-setup.sh`
---------------
should be used with extreme caution. Note that even with this flag set, if
the required zpool was auto-imported by the kernel module, no additional
`zpool import` commands are run, so nothing is forced.
+
+`export-zfs.sh`
+-------------
+
+Normally the zpool containing the root dataset cannot be exported on
+shutdown as it is still in use by the init process. To work around this,
+Dracut is able to restore the initramfs on shutdown and pivot to it.
+All remaining process are then running from a ramdisk, allowing for a
+clean unmount and export of the ZFS root. The theory of operation is
+described in detail in the [Dracut manual](https://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html#_dracut_on_shutdown).
+
+This script will try to export all remaining zpools after Dracut has
+pivoted to the initramfs. If an initial regular export is not successful,
+Dracut will call this script once more with the `final` option,
+in which case a forceful export is attempted.
+
+Other Dracut modules include similar shutdown scripts and Dracut
+invokes these scripts round-robin until they succeed. In particular,
+the `90dm` module installs a script which tries to close and remove
+all device mapper targets. Thus, if there are ZVOLs containing
+dm-crypt volumes or if the zpool itself is backed by a dm-crypt
+volume, the shutdown scripts will try to untangle this.

+ * ARC_mru_ghost - recentely used, no longer in cache
+ * ARC_mfu - frequently used, currently cached
+ * ARC_mfu_ghost - frequently used, no longer in cache
+ * ARC_l2c_only - exists in L2ARC but not other states
+ * When there are no active references to the buffer, they are
+ * are linked onto a list in one of these arc states. These are
+ * the only buffers that can be evicted or deleted. Within each
+ * state there are multiple lists, one for meta-data and one for
+ * non-meta-data. Meta-data (indirect blocks, blocks of dnodes,
+ * etc.) is tracked separately so that it can be managed more
+ * explicitly: favored over data, limited explicitly.
+ *
+ * Anonymous buffers are buffers that are not associated with
+ * a DVA. These are buffers that hold dirty block copies
+ * before they are written to stable storage. By definition,
+ * they are "ref'd" and are considered part of arc_mru
+ * that cannot be freed. Generally, they will aquire a DVA
+ * as they are written and migrate onto the arc_mru list.
+ *
+ * The ARC_l2c_only state is for buffers that are in the second
+ * level ARC but no longer in any of the ARC_m* lists. The second
+ * level ARC itself may also contain buffers that are in any of
+ * the ARC_m* states - meaning that a buffer can exist in two
+ * places. The reason for the ARC_l2c_only state is to keep the
+ * buffer header in the hash table, so that reads that hit the
+ * second level ARC benefit from these fast lookups.

+ * Each metaslab's space is tracked in a single space map in the MOS,

- * we append the allocs and frees from that txg to the space map object.
- * When the txg is done syncing, metaslab_sync_done() updates ms_smo
- * to ms_smo_syncing. Everything in ms_smo is always safe to allocate.
+ * we append the allocs and frees from that txg to the space map.
+ * The pool space is only updated once all metaslabs have finished syncing.
*
- * To load the in-core free map we read the space map object from disk.
+ * To load the in-core free tree we read the space map from disk.
* This object contains a series of alloc and free records that are

- * The Solaris kernel stack size is 24k for x86/x86_64.
- * The Linux kernel stack size is 8k for x86/x86_64.
- *
- * We reduce the default stack size in userspace, to ensure
- * we observe stack overruns in user space as well as in
- * kernel space. In practice we can't set the userspace stack
- * size to 8k because differences in stack usage between kernel
- * space and userspace could lead to spurious stack overflows
- * (especially when debugging is enabled). Nevertheless, we try
- * to set it to the lowest value that works (currently 8k*4).
- * PTHREAD_STACK_MIN is the minimum stack required for a NULL
- * procedure in user space and is added in to the stack
- * requirements.
- *
- * Some buggy NPTL threading implementations include the
- * guard area within the stack size allocations. In
- * this case we allocate an extra page to account for the
- * guard area since we only have two pages of usable stack
- * on Linux.
+ * We allow the default stack size in user space to be specified by
+ * setting the ZFS_STACK_SIZE environment variable. This allows us
+ * the convenience of observing and debugging stack overruns in
+ * user space. Explicitly specified stack sizes will be honored.
+ * The usage of ZFS_STACK_SIZE is discussed further in the

This utility pokes configuration changes directly into a ZFS pool,
which is dangerous and can cause data corruption.

+.B "ZFS_STACK_SIZE=stacksize"
+Limit the default stack size to \fBstacksize\fR bytes for the purpose of
+detecting and debugging kernel stack overflows. For x86_64 platforms this
+value should be set as follows to simulate these platforms: \fB8192\fR
+(Linux), \fB20480\fR (Illumos), \fB16384\fR (FreeBSD).
+
+In practice you may need to set these value slightly higher because
+differences in stack usage between kernel and user space can lead to spurious
+stack overflows (especially when debugging is enabled). The specified value
+will be rounded up to a floor of PTHREAD_STACK_MIN which is the minimum stack
+required for a NULL procedure in user space.
+
+By default the stack size is limited to 256K.

+.SH NAME
+zfs\-events \- Events created by the ZFS filesystem.
+.SH DESCRIPTION
+.sp
+.LP
+Description of the different events generated by the ZFS stack.
+.sp
+Most of these don't have any description. The events generated by ZFS
+have never been publicly documented. What is here is intended as a
+starting point to provide documentation for all possible events.
+.sp
+To view all events created since the loading of the ZFS infrastructure
+(i.e, "the module"), run
+.P
+.nf
+\fBzpool events\fR
+.fi
+.P
+to get a short list, and
+.P
+.nf
+\fBzpool events -v\fR
+.fi
+.P
+to get a full detail of the events and what information
+is available about it.
+.sp
+This man page lists the different subclasses that are issued
+in the case of an event. The full event name would be
+\fIereport.fs.zfs.SUBCLASS\fR, but we only list the last
+part here.

+\fBzfs_free_leak_on_eio\fR (int)
+.ad
+.RS 12n
+If destroy encounters an EIO while reading metadata (e.g. indirect
+blocks), space referenced by the missing metadata can not be freed.
+Normally this causes the background destroy to become "stalled", as
+it is unable to make forward progress. While in this stalled state,
+all remaining space to free from the error-encountering filesystem is
+"temporarily leaked". Set this flag to cause it to ignore the EIO,
+permanently leak the space from indirect blocks that can not be read,
+and continue to free everything else that it can.
+
+The default, "stalling" behavior is useful if the storage partially
+fails (i.e. some but not all i/os fail), and then later recovers. In
+this case, we will be able to continue pool operations while it is
+partially failed, and when it recovers, we can continue to free the
+space, with no leaks. However, note that this case is actually
+fairly rare.
+
+Typically pools either (a) fail completely (but perhaps temporarily,
+e.g. a top-level vdev going offline), or (b) have localized,
+permanent errors (e.g. disk returns the wrong data due to bit flip or
+firmware bug). In case (a), this setting does not matter because the
+pool will be suspended and the sync thread will not be able to make
+forward progress regardless. In case (b), because the error is
+permanent, the best we can do is leak the minimum amount of space,
+which is what setting this flag will do. Therefore, it is reasonable
+for this flag to normally be set, but we chose the more conservative
+approach of not setting it, so that there is no possibility of
+leaking space in the "partial temporary" failure case.

-pool (even before any data is written). Since this feature is not
+pool using the \fBzfs\fR(1M) command. Also, all newly written metadata
+will be compressed with \fBlz4\fR algorithm. Since this feature is not
read-only compatible, this operation will render the pool unimportable
-on systems without support for the \fBlz4_compress\fR feature. At the
-moment, this operation cannot be reversed. Booting off of
-\fBlz4\fR-compressed root pools is supported.

+
+This feature improves performance of incremental sends ("zfs send -i")
+and receives for objects with many holes. The most common case of
+hole-filled objects is zvols.
+
+An incremental send stream from snapshot \fBA\fR to snapshot \fBB\fR
+contains information about every block that changed between \fBA\fR and
+\fBB\fR. Blocks which did not change between those snapshots can be
+identified and omitted from the stream using a piece of metadata called
+the 'block birth time', but birth times are not recorded for holes (blocks
+filled only with zeroes). Since holes created after \fBA\fR cannot be
+distinguished from holes created before \fBA\fR, information about every
+hole in the entire filesystem or zvol is included in the send stream.
+
+For workloads where holes are rare this is not a problem. However, when
+incrementally replicating filesystems or zvols with many holes (for
+example a zvol formatted with another filesystem) a lot of time will
+be spent sending and receiving unnecessary information about holes that
+already exist on the receiving side.
+
+Once the \fBhole_birth\fR feature has been enabled the block birth times
+of all new holes will be recorded. Incremental sends between snapshots
+created after this feature is enabled will use this new metadata to avoid
+sending information about holes that already exist on the receiving side.
+
+This feature becomes \fBactive\fR as soon as it is enabled and will
+never return to being \fBenabled\fB.

+
+This feature improves the performance and compression ratio of
+highly-compressible blocks. Blocks whose contents can compress to 112 bytes
+or smaller can take advantage of this feature.
+
+When this feature is enabled, the contents of highly-compressible blocks are
+stored in the block "pointer" itself (a misnomer in this case, as it contains
+the compresseed data, rather than a pointer to its location on disk). Thus
+the space of the block (one sector, typically 512 bytes or 4KB) is saved,
+and no additional i/o is needed to read and write the data block.
+
+This feature becomes \fBactive\fR as soon as it is enabled and will
+never return to being \fBenabled\fR.

+
+.SH ZEVENTS
+.PP
+A zevent is comprised of a list of nvpairs (name/value pairs). Each zevent
+contains an EID (Event IDentifier) that uniquely identifies it throughout
+the lifetime of the loaded ZFS kernel module; this EID is a monotonically
+increasing integer that resets to 1 each time the kernel module is loaded.
+Each zevent also contains a class string that identifies the type of event.
+For brevity, a subclass string is defined that omits the leading components
+of the class string. Additional nvpairs exist to provide event details.
+.PP
+The kernel maintains a list of recent zevents that can be viewed (along with
+their associated lists of nvpairs) using the "\fBzpool events \-v\fR" command.
+
+.SH CONFIGURATION
+.PP
+ZEDLETs to be invoked in response to zevents are located in the
+\fIenabled-zedlets\fR directory. These can be symlinked or copied from the
+\fIinstalled-zedlets\fR directory; symlinks allow for automatic updates
+from the installed ZEDLETs, whereas copies preserve local modifications.
+As a security measure, ZEDLETs must be owned by root. They must have
+execute permissions for the user, but they must not have write permissions
+for group or other. Dotfiles are ignored.
+.PP
+ZEDLETs are named after the zevent class for which they should be invoked.
+In particular, a ZEDLET will be invoked for a given zevent if either its
+class or subclass string is a prefix of its filename (and is followed by
+a non-alphabetic character). As a special case, the prefix "all" matches
+all zevents. Multiple ZEDLETs may be invoked for a given zevent.
+
+.SH ZEDLETS
+.PP
+ZEDLETs are executables invoked by the ZED in response to a given zevent.
+They should be written under the presumption they can be invoked concurrently,
+and they should use appropriate locking to access any shared resources.
+Common variables used by ZEDLETs can be stored in the default rc file which
+is sourced by scripts; these variables should be prefixed with "ZED_".
+.PP
+The zevent nvpairs are passed to ZEDLETs as environment variables.
+Each nvpair name is converted to an environment variable in the following
+manner: 1) it is prefixed with "ZEVENT_", 2) it is converted to uppercase,
+and 3) each non-alphanumeric character is converted to an underscore.
+Some additional environment variables have been defined to present certain
+nvpair values in a more convenient form. An incomplete list of zevent
+environment variables is as follows:
+.TP
+.B
+ZEVENT_EID
+The Event IDentifier.
+.TP
+.B
+ZEVENT_CLASS
+The zevent class string.
+.TP
+.B
+ZEVENT_SUBCLASS
+The zevent subclass string.
+.TP
+.B
+ZEVENT_TIME
+The time at which the zevent was posted as
+"\fIseconds\fR\ \fInanoseconds\fR" since the Epoch.
+.TP
+.B
+ZEVENT_TIME_SECS
+The \fIseconds\fR component of ZEVENT_TIME.
+.TP
+.B
+ZEVENT_TIME_NSECS
+The \fInanoseconds\fR component of ZEVENT_TIME.
+.TP
+.B
+ZEVENT_TIME_STRING
+An almost-RFC3339-compliant string for ZEVENT_TIME.
+.PP
+Additionally, the following ZED & ZFS variables are defined:
+.TP
+.B
+ZED_PID
+The daemon's process ID.
+.TP
+.B
+ZED_ZEDLET_DIR
+The daemon's current \fIenabled-zedlets\fR directory.
+.TP
+.B
+ZFS_ALIAS
+The ZFS alias (\fIname-version-release\fR) string used to build the daemon.
+.TP
+.B
+ZFS_VERSION
+The ZFS version used to build the daemon.
+.TP
+.B
+ZFS_RELEASE
+The ZFS release used to build the daemon.
+.PP
+ZEDLETs may need to call other ZFS commands. The installation paths of
+the following executables are defined: \fBZDB\fR, \fBZED\fR, \fBZFS\fR,
+\fBZINJECT\fR, and \fBZPOOL\fR. These variables can be overridden in the
+rc file if needed.
+
+.SH FILES
+.\" .TP
+.\" @sysconfdir@/zfs/zed.conf
+.\" The default configuration file for the daemon.
+.TP
+.I @sysconfdir@/zfs/zed.d
+The default directory for enabled ZEDLETs.
+.TP

+.TP

+The default file containing the daemon's state.
+
+.SH SIGNALS
+.TP
+.B HUP
+Reconfigure the daemon and rescan the directory for enabled ZEDLETs.
+.TP
+.B TERM
+Terminate the daemon.
+
+.SH NOTES
+.PP
+\fBZED\fR requires root privileges.
+.\" Do not taunt zed.
+
+.SH BUGS
+.PP
+Events are processed synchronously by a single thread. This can delay the
+processing of simultaneous zevents.
+.PP
+There is no maximum timeout for ZEDLET execution. Consequently, a misbehaving
+ZEDLET can delay the processing of subsequent zevents.
+.PP
+The ownership and permissions of the \fIenabled-zedlets\fR directory (along
+with all parent directories) are not checked. If any of these directories
+are improperly owned or permissioned, an unprivileged user could insert a
+ZEDLET to be executed as root. The requirement that ZEDLETs be owned by
+root mitigates this to some extent.
+.PP
+ZEDLETs are unable to return state/status information to the kernel.
+.PP
+Some zevent nvpair types are not handled. These are denoted by zevent
+environment variables having a "_NOT_IMPLEMENTED_" value.
+.PP
+Internationalization support via gettext has not been added.
+.PP
+The configuration file is not yet implemented.
+.PP
+The diagnosis engine is not yet implemented.

.SS "Deduplication"
.LP
Deduplication is the process for removing redundant data at the block-level, reducing the total amount of data stored. If a file system has the \fBdedup\fR property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored and common components are shared among files.
+.sp
+\fBWARNING: DO NOT ENABLE DEDUPLICATION UNLESS YOU NEED IT AND KNOW EXACTLY WHAT YOU ARE DOING!\fR
+.sp
+Deduplicating data is a very resource-intensive operation. It is generally recommended that you have \fIat least\fR 1.25 GB of RAM per 1 TB of storage when you enable deduplication. But calculating the exact requirenments is a somewhat complicated affair. Please see the \fBOracle Dedup Guide\fR for more information..
+.sp
+Enabling deduplication on an improperly-designed system will result in extreme performance issues (extremely slow filesystem and snapshot deletions etc.) and can potentially lead to data loss (i.e. unimportable pool due to memory exhaustion) if your system is not built for this purpose. Deduplication affects the processing power (CPU), disks (and the controller) as well as primary (real) memory.
+.sp
+Before creating a pool with deduplication enabled, ensure that you have planned your hardware requirements appropriately and implemented appropriate recovery practices, such as regular backups.
+.sp
+Unless necessary, deduplication should NOT be enabled on a system. Instead, consider using \fIcompression=lz4\fR, as a less resource-intensive alternative.
.SS "Native Properties"
.LP
Properties are divided into two types, native properties and user-defined (or "user") properties. Native properties either export internal statistics or control \fBZFS\fR behavior. In addition, native properties are either editable or read-only. User properties have no effect on \fBZFS\fR behavior, but you can use them to annotate datasets in a way that is meaningful in your environment. For more information about user properties, see the "User Properties" section, below.
Controls whether deduplication is in effect for a dataset. The default value is \fBoff\fR. The default checksum used for deduplication is \fBsha256\fR (subject to change). When \fBdedup\fR is enabled, the \fBdedup\fR checksum algorithm overrides the \fBchecksum\fR property. Setting the value to \fBverify\fR is equivalent to specifying \fBsha256,verify\fR.
.sp
If the property is set to \fBverify\fR, then, whenever two blocks have the same signature, ZFS will do a byte-for-byte comparison with the existing block to ensure that the contents are identical.
+.sp
+Unless necessary, deduplication should NOT be enabled on a system. See \fBDeduplication\fR above.

+.RS 4n
+Controls what types of metadata are stored redundantly. ZFS stores an
+extra copy of metadata, so that if a single block is corrupted, the
+amount of user data lost is limited. This extra copy is in addition to
+any redundancy provided at the pool level (e.g. by mirroring or RAID-Z),
+and is in addition to an extra copy specified by the \fBcopies\fR
+property (up to a total of 3 copies). For example if the pool is
+mirrored, \fBcopies\fR=2, and \fBredundant_metadata\fR=most, then ZFS
+stores 6 copies of most metadata, and 4 copies of data and some

Pool sector size exponent, to the power of 2 (internally referred to as "ashift"). I/O operations will be aligned to the specified size boundaries. Additionally, the minimum (disk) write size will be set to the specified size, so this represents a space vs. performance trade-off. The typical case for setting this property is when performance is important and the underlying disks use 4KiB sectors but report 512B sectors to the OS (for compatibility reasons); in that case, set \fBashift=12\fR (which is 1<<12 = 4096).

- * etc.) is tracked separately so that it can be managed more
- * explicitly: favored over data, limited explicitly.
- *
- * Anonymous buffers are buffers that are not associated with
- * a DVA. These are buffers that hold dirty block copies
- * before they are written to stable storage. By definition,
- * they are "ref'd" and are considered part of arc_mru
- * that cannot be freed. Generally, they will aquire a DVA
- * as they are written and migrate onto the arc_mru list.
- *
- * The ARC_l2c_only state is for buffers that are in the second
- * level ARC but no longer in any of the ARC_m* lists. The second
- * level ARC itself may also contain buffers that are in any of
- * the ARC_m* states - meaning that a buffer can exist in two
- * places. The reason for the ARC_l2c_only state is to keep the
- * buffer header in the hash table, so that reads that hit the
- * second level ARC benefit from these fast lookups.

+ * Embedded-data Block Pointers
+ *
+ * Normally, block pointers point (via their DVAs) to a block which holds data.
+ * If the data that we need to store is very small, this is an inefficient
+ * use of space, because a block must be at minimum 1 sector (typically 512
+ * bytes or 4KB). Additionally, reading these small blocks tends to generate
+ * more random reads.
+ *
+ * Embedded-data Block Pointers allow small pieces of data (the "payload",
+ * up to 112 bytes) to be stored in the block pointer itself, instead of
+ * being pointed to. The "Pointer" part of this name is a bit of a
+ * misnomer, as nothing is pointed to.
+ *
+ * BP_EMBEDDED_TYPE_DATA block pointers allow highly-compressible data to
+ * be embedded in the block pointer. The logic for this is handled in
+ * the SPA, by the zio pipeline. Therefore most code outside the zio
+ * pipeline doesn't need special-cases to handle these block pointers.
+ *
+ * See spa.h for details on the exact layout of embedded block pointers.

- * Space map reference trees.

- * as opposed to the implicit reference count of 0 or 1 in a space map.
- * This representation comes in handy when computing the union or

- * N space maps is the subset of the reference tree with refcnt >= 1.
- * The intersection of N space maps is the subset with refcnt >= N.
- *
- * [It's very much like a Fourier transform. Unions and intersections
- * are hard to perform in the 'space map domain', so we convert the maps
- * into the 'reference count domain', where it's trivial, then invert.]
- *
- * vdev_dtl_reassess() uses computations of this form to determine
- * DTL_MISSING and DTL_OUTAGE for interior vdevs -- e.g. a RAID-Z vdev
- * has an outage wherever refcnt >= vdev_nparity + 1, and a mirror vdev

+ * A range tree is a collection of integers. Every integer is either

+ * the idea: it allows its members to have arbitrary reference counts,
+ * as opposed to the implicit reference count of 0 or 1 in a range tree.
+ * This representation comes in handy when computing the union or
+ * intersection of multiple space maps. For example, the union of
+ * N range trees is the subset of the reference tree with refcnt >= 1.
+ * The intersection of N range trees is the subset with refcnt >= N.
+ *
+ * [It's very much like a Fourier transform. Unions and intersections
+ * are hard to perform in the 'range tree domain', so we convert the trees
+ * into the 'reference count domain', where it's trivial, then invert.]
+ *
+ * vdev_dtl_reassess() uses computations of this form to determine
+ * DTL_MISSING and DTL_OUTAGE for interior vdevs -- e.g. a RAID-Z vdev

-Detect a ZFS filesystem by looking for valid uberblocks.
-
-This support will appear in an upstream version of e2fsprogs. For the
-moment however you will still need to locally patch you e2fsprogs packages.
-This patch applies cleanly to fc11's e2fsprogs-*-1.41.4-10 and should
-apply easily enough to the e2fsprogs from other distros.

+%description -n libnvpair1
+This package contains routines for packing and unpacking name-value
+pairs. This functionality is used to portably transport data across
+process boundaries, between kernel and user space, and can be used
+to write self describing data structures on disk.

+%description -n libuutil1
+This library provides a variety of compatibility functions for ZFS on Linux:
+ * libspl: The Solaris Porting Layer userland library, which provides APIs
+ that make it possible to run Solaris user code in a Linux environment
+ with relatively minimal modification.
+ * libavl: The Adelson-Velskii Landis balanced binary tree manipulation
+ library.
+ * libefi: The Extensible Firmware Interface library for GUID disk
+ partitioning.
+ * libshare: NFS, SMB, and iSCSI service integration for ZFS.

+# Verify that an assortment of known good reference pools can be imported
+# using different versions of the ZoL code.
+#
+# By default references pools for the major ZFS implementation will be
+# checked against the most recent ZoL tags and the master development branch.
+# Alternate tags or branches may be verified with the '-s <src-tag> option.
+# Passing the keyword "installed" will instruct the script to test whatever
+# version is installed.
+#
+# Preferentially a reference pool is used for all tests. However, if one
+# does not exist and the pool-tag matches one of the src-tags then a new
+# reference pool will be created using binaries from that source build.
+# This is particularly useful when you need to test your changes before
+# opening a pull request. The keyword 'all' can be used as short hand
+# refer to all available reference pools.
+#
+# New reference pools may be added by placing a bzip2 compressed tarball
+# of the pool in the scripts/zfs-images directory and then passing
+# the -p <pool-tag> option. To increase the test coverage reference pools
+# should be collected for all the major ZFS implementations. Having these
+# pools easily available is also helpful to the developers.
+#
+# Care should be taken to run these tests with a kernel supported by all
+# the listed tags. Otherwise build failure will cause false positives.

+# EXAMPLES:
+#
+# The following example will verify the zfs-0.6.2 tag, the master branch,
