We want to be able to run channel programs outside of synching context.
This would greatly improve performance of channel program that just gather
information, as we won't have to wait for synching context anymore.
This feature should introduce the following:
- A new command line flag in "zfs program" to specify our intention to
run in open context.
- A new flag/option within the channel program ioctl which selects the
context.
- Appropriate error handling whenever we try a channel program in
open-context that contains zfs.sync* expressions.
- Documentation for the new feature in the manual pages.

We can't link an executable using -m32 until the lib32 phase of a

cddl/usr.sbin/dtrace/tests. Some other solution will need to be found.
SPA_MAXBLOCKSIZE is 16 MB and having such a large object on the stack is
not nice in general and it could cause some confusing failures in the
single-user mode where the default stack size of 8 MB is used.

The test creates a D library with a "depends_on library" pragma
referencing a non-existent library, and expects compilation to fail.
However, as far as I can tell, libdtrace is supposed simply abort
compilation of the library in this case, and continue. This behaviour
is desirable when adding libraries which depend on optional KLDs, for
example.

When we encounter a USDT probe in a weak symbol, we emit an alias for

du(1), df(1m), ls(1), and swap(1m) all include a copy (it appears literally
copied) of the 'number_to_scaled_string' function in their source. This should
be moved to a shared library and all 4 commands should use this instead.
FreeBSD note: of all libcmdutils functionality ZFS (and other illumos
contrib code) currently uses only nicenum() function (which is similar
to humanize_number but has some formatting differences). For this
reason I decided to not port the whole library. As a result, nicenum.c
from libcmdutils is compiled into libzfs and libzpool. This is a bit
ugly, but works. If one day we are forced to create libillumos, then
the file should be moved to that library.

The zfs diff command presents a description of the changes that have occurred
to files within a filesystem between two snapshots. If a file is renamed, the
tool is capable of reporting this, e.g.:
cd /some/zfs/dataset/subdir
mv file0 file1
Will result in a diff record like:
R /some/zfs/dataset/subdir/file0 -> /some/zfs/dataset/subdir/file1
Unfortunately, it seems that rename detection only uses the base filename to
determine if a file has been renamed or simply modified. This leads to
misreporting only the original filename, omitting the more relevant destination
filename entirely. For example:
cd /some/zfs/dataset/subdir
mv file0 ../otherdir/file0
Will result in a diff entry:
M /some/zfs/dataset/subdir/file0
But it should really emit:
R /some/zfs/dataset/subdir/file0 -> /some/zfs/dataset/otherdir/file0

zdb is very handy for diagnosing problems with a pool in a safe and

illumos/illumos-gate@1271e4b10d1271e4b10dhttps://www.illumos.org/issues/8585
The current implementation of zil_commit() can introduce significant
latency, beyond what is inherent due to the latency of the underlying
storage. The additional latency comes from two main problems:
1. When there's outstanding ZIL blocks being written (i.e. there's
already a "writer thread" in progress), then any new calls to
zil_commit() will block waiting for the currently oustanding ZIL
blocks to complete. The blocks written for each "writer thread" is
coined a "batch", and there can only ever be a single "batch" being
written at a time. When a batch is being written, any new ZIL
transactions will have to wait for the next batch to be written,
which won't occur until the current batch finishes.
As a result, the underlying storage may not be used as efficiently
as possible. While "new" threads enter zil_commit() and are blocked
waiting for the next batch, it's possible that the underlying
storage isn't fully utilized by the current batch of ZIL blocks. In
that case, it'd be better to allow these new threads to generate
(and issue) a new ZIL block, such that it could be serviced by the
underlying storage concurrently with the other ZIL blocks that are
being serviced.
2. Any call to zil_commit() must wait for all ZIL blocks in its "batch"
to complete, prior to zil_commit() returning. The size of any given
batch is proportional to the number of ZIL transaction in the queue
at the time that the batch starts processing the queue; which
doesn't occur until the previous batch completes. Thus, if there's a
lot of transactions in the queue, the batch could be composed of
many ZIL blocks, and each call to zil_commit() will have to wait for
all of these writes to complete (even if the thread calling
zil_commit() only cared about one of the transactions in the batch).
