-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

+dnl # Read meta data from the META file. When building from a git repository
+dnl # the ZFS_META_RELEASE field will be overwritten if there is an annotated
+dnl # tag matching the form ZFS_META_NAME-ZFS_META_VERSION-*. This allows
+dnl # for working builds to be uniquely identified using the git commit hash.
+dnl #
+dnl # The META file format is as follows:
+dnl # ^[ ]*KEY:[ \t]+VALUE$
+dnl #
+dnl # In other words:
+dnl # - KEY is separated from VALUE by a colon and one or more spaces/tabs.
+dnl # - KEY and VALUE are case sensitive.
+dnl # - Leading spaces are ignored.
+dnl # - First match wins for duplicate keys.
+dnl #
+dnl # A line can be commented out by preceding it with a '#' (or technically
+dnl # any non-space character since that will prevent the regex from
+dnl # matching).
+dnl #
+dnl # WARNING:
+dnl # Placing a colon followed by a space or tab (ie, ":[ \t]+") within the
+dnl # VALUE will prematurely terminate the string since that sequence is
+dnl # used as the awk field separator.
+dnl #
+dnl # KEYS:
+dnl # The following META keys are recognized:
+dnl # Name, Version, Release, Date, Author, LT_Current, LT_Revision, LT_Age

- * which itself is a buffer for ARC eviction. The thread that does this is

+ * found during scanning and selected for writing to an L2ARC device, we
+ * temporarily boost scanning headroom during the next scan cycle to make
+ * sure we adapt to compression effects (which might significantly reduce
+ * the data volume we write to L2ARC). The thread that does this is
* l2arc_feed_thread(), illustrated below; example sizes are included to
* provide a better sense of ratio than this diagram:
*
* l2arc_write_max max write bytes per interval
* l2arc_write_boost extra write bytes during device warmup
* l2arc_noprefetch skip caching prefetched buffers
+ * l2arc_nocompress skip compressing buffers
* l2arc_headroom number of max device writes to precache
+ * l2arc_headroom_boost when we find compressed buffers during ARC
+ * scanning, we multiply headroom by this
+ * percentage factor for the next scan cycle,
+ * since more compressed buffers are likely to
+ * be present
* l2arc_feed_secs seconds between L2ARC writing
