I read the following article and noticed a couple of ZFS bugs mentioned:
https://pvs-studio.com/en/blog/posts/cpp/0377/
I decided to search for them in the modern OpenZFS codebase and then
found one that matched the description of the first one:
V593 Consider reviewing the expression of the 'A = B != C' kind. The
expression is calculated as following: 'A = (B != C)'. zfs_vfsops.c 498
The consequence of this is that the error value is replaced with `1`
when there is an error. When there is no error, 0 is correctly passed.
This is a very minor issue that is unlikely to cause any real problems.
The incorrect error code would either be returned to the mount command
on a failure or any of `zfs receive`, `zfs recv`, `zfs rollback` or `zfs
upgrade`.
The second one has already been fixed.

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).

Currently, if API tests fail, we either ignore the failures, or

incompatibilities with existing APIs may develop, but not trip the
configure compatibility checks.
This introduces a new mechanism to require APIs for kernels above a
particular version. While not perfect, this at least guarantees
mainline kernels do not break existing APIs without at least providing

commit a7304ab9c1 upstream
mmapwrite is used during the ZTS to identify issues with mmap-ed files.
This helper program exercises this pathway by continuously writing to a
file. ee6bf97c7 modified the writing threads to terminate after a set
amount of total data is written. This change allows standard program
execution to reach the end of a writer thread without closing the file
descriptor, introducing a resource "leak."
This patch appeases resource leak analyses by close()-ing the file at
the end of the thread.

commit ee6bf97c77 upstream
mmapwrite spawns several threads, all of which perform writes on a file
for the purpose of testing the behavior of mmap(2)-ed files. One
thread performs an mmap and a write to the beginning of that region,
while the others perform regular writes after lseek(2)-ing the end of
the file.
Because these regular writes are set in a while (1) loop, they will
write an unbounded amount of data to disk. The mmap_write_001_pos test
script SIGKILLs them after 30 seconds, but on fast testbeds, this may
be enough time to exhaust the available space in the filesystem,
leading to spurious test failures.
Instead, limit the total file size by checking that the lseek return
value is no greater than 250 * 1024*1024 bytes, which is less than the
default minimum vdev size defined in includes/default.cfg .
This also includes part of 2a493a4c71,
which checks the return value of lseek.

The original ARC paper called for an initial 50/50 MRU/MFU split
and this is accounted in various places where arc_p = arc_c >> 1,
with further adjustment based on ghost lists size/hit. However, in
current code both arc_adapt() and arc_get_data_impl() aggressively
grow arc_p until arc_c is reached, causing unneeded pressure on
MFU and greatly reducing its scan-resistance until ghost list
adjustments kick in.
This patch restores the original behavior of initially having arc_p
as 1/2 of total ARC, without preventing MRU to use up to 100% total
ARC when MFU is empty.

https://github.com/openzfs/zfs/issues/10891) outlining the problem and
potential solutions.
With the proper solutions being significant in terms of complexity and
the priority of the issue being low for the time being, this patch
exposes `zfs_vdev_open_timeout_ms` as a tunable so people that are
