ZFS_IOC_COUNT_FILLED does unnecessary txg_wait_synced()
`lseek(SEEK_DATA | SEEK_HOLE)` are only accurate when the on-disk blocks
reflect all writes, i.e. when there are no dirty data blocks. To ensure
this, if the target dnode is dirty, they wait for the open txg to be
synced, so we can call them "stabilizing operations". If they cause
txg_wait_synced often, it can be detrimental to performance.
Typically, a group of files are all modified, and then SEEK_DATA/HOLE
are performed on them. In this case, the first SEEK does a
txg_wait_synced(), and subsequent SEEKs don't need to wait, so
performance is good.
However, if a workload involves an interleaved metadata modification,
the subsequent SEEK may do a txg_wait_synced() unnecessarily. For
example, if we do a `read()` syscall to each file before we do its SEEK.
This applies even with `relatime=on`, when the `read()` is the first
read after the last write. The txg_wait_synced() is unnecessary because
the SEEK operations only care that the structure of the tree of indirect
and data blocks is up to date on disk. They don't care about metadata
like the contents of the bonus or spill blocks. (They also don't care
if an existing data block is modified, but this would be more involved
to filter out.)
This commit changes the behavior of SEEK_DATA/HOLE operations such that
they do not call txg_wait_synced() if there is only a pending change to
the bonus or spill block.

Introduce minimal ZIL block commit delay
Despite all optimizations, tests on actual hardware show that FreeBSD
kernel can't sleep for less then ~2us. Similar tests on Linux show
~50us delay at least from nanosleep() (haven't tested inside kernel).
It means that on very fast log device ZIL may not be able to satisfy
zfs_commit_timeout_pct block commit timeout, increasing log latency
more than desired.
Handle that by introduction of zil_min_commit_timeout parameter,
specifying minimal timeout value where additional delays to aggregate
writes may be skipped. Also skip delays if the LWB is more than 7/8
full, that often happens if I/O sizes are constant and match one of
LWB sizes. Both things are applied only if there were no already
outstanding log blocks, that may indicate single-threaded workload,
that by definition can not benefit from the commit delays.
While there, add short time moving average to zl_last_lwb_latency to
make it more stable.

Optimize microzaps
Microzap on-disk format does not include a hash tree, expecting one to
be built in RAM during mzap_open(). The built tree is linked to DMU
user buffer, freed when original DMU buffer is dropped from cache. I've
found that workloads accessing many large directories and having active
eviction from DMU cache spend significant amount of time building and
then destroying the trees. I've also found that for each 64 byte mzap
element additional 64 byte tree element is allocated, that is a waste
of memory and CPU caches.
Improve memory efficiency of the hash tree by switching from AVL-tree
to B-tree. It allows to save 24 bytes per element just on pointers.
Save 32 bits on mze_hash by storing only upper 32 bits since lower 32
bits are always zero for microzaps. Save 16 bits on mze_chunkid, since
microzap can never have so many elements. Respectively with the 16 bits
there can be no more than 16 bits of collision differentiators. As
result, struct mzap_ent now drops from 48 (rounded to 64) to 8 bytes.
Tune B-trees for small data. Reduce BTREE_CORE_ELEMS from 128 to 126
to allow struct zfs_btree_core in case of 8 byte elements to pack into
2KB instead of 4KB. Aside of the microzaps it should also help 32bit
range trees. Allow custom B-tree leaf size to reduce memmove() time.
Split zap_name_alloc() into zap_name_alloc() and zap_name_init_str().
It allows to not waste time allocating/freeing memory when processing
multiple names in a loop during mzap_open().
Together on a pool with 10K directories of 1800 files each and DMU
cache limited to 128MB this reduces time of `find . -name zzz` by 41%
from 7.63s to 4.47s, and saves additional ~30% of CPU time on the DMU
cache reclamation.

Illumos-commit: https://github.com/illumos/illumos-gate/commit/f137b22e734e85642da3e56e8b94da3f5f027c73
Porting Notes:
The patch in illumos did not have much of a commit message, and did not
provide attribution to the reporter, while original patch proposed to
OpenZFS did, so I am listing the reporter (myself) and original patch
author (also myself) below while including the original commit message
with some minor corrections as part of the porting notes:
There, we have type promotion from int8_t to size_t, which is unsigned.
C will sign extend the value as part of the widening before treating the
value as unsigned and the negative values we can counter are error
values from U8_ILLEGAL_CHAR and U8_OUT_OF_RANGE_CHAR, which are -1 and
-2 respectively. The unsigned versions of these under two's complement
are SIZE_MAX and SIZE_MAX-1 respectively.
The bounds check is written under the assumption that `size <= 1` does a
signed comparison. This is followed by a pointer comparison to see if
the string has the correct length, which is fine.
A little further down we have:
for (i = 0; i < size; i++)
tc[i] = *p++;
When an error condition is encountered, this will attempt to iterate at
least SIZE_MAX-1 times, which will massively overflow the buffer, which
is not fine.
The kernel will kill the loop as soon as it hits the kernel stack guard
on Linux systems built with CONFIG_VMAP_STACK=y, which should be just
about all of them. That prevents arbitrary code execution and just about
any other bad thing that a black hat attacker might attempt with
knowledge of this buffer overflow. Other systems' kernels have
mitigations for unbounded in-kernel buffer overflows that will catch
this too.
Also, the patch in illumos-gate made an effort to fix C style issues
that had been fixed in the OpenZFS/ZFSOnLinux repository. Those issues
had been mentioned in the email that I originally sent them about this
issue. One of the fixes had not been already done, so it is included.
Another to collect_a_seq()'s arguments was handled differently in
OpenZFS. For the sake of avoiding unnecessary differences, it has been
adopted. This has the interesting effect that if you correct the paths
in the illumos-gate patch to match the current OpenZFS repository, you
can reverse apply it cleanly.

ztest fails assertion in zio_write_gang_member_ready()
Encrypted blocks can have up to 2 DVA's, as the third DVA is reserved
for the salt+IV. However, dmu_write_policy() allows non-encrypted
blocks (e.g. DMU_OT_OBJSET) inside encrypted datasets to request and
allocate 3 DVA's, since they don't need a salt+IV (they are merely
authenicated).
However, if such a block becomes a gang block, the gang code incorrectly
limits the gang block header to 2 DVA's. This leads to a "NDVAs
inversion", where a parent block (the gang block header) has less DVA's
than its children (the gang members), causing an assertion failure in
zio_write_gang_member_ready().
This commit addresses the problem by only restricting the gang block
header to 2 DVA's if the block is actually encrypted (and thus its gang
block members can have at most 2 DVA's).

exponentiation was replaced with a bit shift. Unfortunately, it did not
handle negative values. Also, it only supported exponents numbers with
7 digits before before overflow. This supports exponents up to 15 digits
before overflow.
Clang's static analyzer reported this as "Result of operation is garbage
or undefined" because the exponent was negative.
