The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.
I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.
Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.
Improvements include:
project quotas, encrypted datasets,
allocation classes, vectorized raidz,
vectorized checksums, various command line
improvements, zstd compression.
Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

Port the following ZFS commits from ZoL to illumos.
379ca9cf2 Multi-modifier protection (MMP)
bbffb59ef Fix multihost stale cache file import
0d398b256 Do not initiate MMP writes while pool is suspended
10701 Correct lock ASSERTs in vdev_label_read/write

https://www.illumos.org/issues/10701
Port of ZoL commit:
0091d66f4e Correct lock ASSERTs in vdev_label_read/write
At a minimum, this fixes a blown assert during an MMP test run when running on
a DEBUG build.
11770 additional mmp fixes

https://www.illumos.org/issues/11770
Port a few additional MMP fixes from ZoL that came in after our
initial MMP port.
4ca457b065 ZTS: Fix mmp_interval failure
ca95f70dff zpool import progress kstat
(only minimal changes from above can be pulled in right now)
060f0226e6 MMP interval and fail_intervals in uberblock
Note from the committer (me).
I do not have any use for this feature and I have not tested it. I only
did smoke testing with multihost=off.
Please be aware.
I merged the code only to make future merges easier.

Callers of dsl_dataset_name pass a buffer of size ZFS_MAXNAMELEN, but
dsl_dataset_name copies the datasets' name PLUS the snapshot name to it,
resulting in a max of 2 * ZFS_MAXNAMELEN + '@'.

A ZFS feature flags (large blocks) tracks its refcounts as the number of
datasets that have ever used the feature. Several features of this type
are planned to be added (new checksum functions). This code should be made
common infrastructure rather than duplicating the code for each feature.

Use reserved space for ZFS administrative commands.
We reserve 1/2^spa_slop_shift = 1/32 or 3.125% of pool space (or 32MB at
least) for system use. Most ZPL operations, e.g. write(2), creat(2), will
fail with ENOSPC if we fall below this.
Certain operations, e.g. file removal and most administrative actions,
still permitted until half of the slop space is used. This would allow
users to use these operations to free up space in the pool when pool is
close to full but half of slop space is still free.
A very restricted set of operations that frees up space or change quota
are always permitted, regardless of the amount of free space.
