Citing Kirk:
The previous code [before 8563de2f27 -- kib] did not call
vnode_pager_setsize() but worked because later in ffs_snapshot() it
does a UFS_WRITE() to output the snaplist. Previously the UFS_WRITE()
allocated the extra block at the end of the file which caused it to do
the needed vnode_pager_setsize(). But the new code had already allocated
the extra block, so UFS_WRITE() did not extend the size and thus did not
do the vnode_pager_setsize().

Since 4581cefc1e
ATF opens the results file on startup. This fixes problems like
capsicumized tests not being able to open the file on exit.
However, this test closes all file descriptors just to check that
socketpair returns fd 3+4 and thereby also closes the ATF results file.
This then results in an EBADF when writing the result so the test is
reported as broken.
While system calls that create new file descriptors (must?) use the lowest
available file descriptor number, it does not seem useful to test this
property here. Drop the check for FD==3/4 to unbreak the testsuite.
We could also try to re-open the results file in ATF if we get a EBADF
error, but that will fail when running under Capsicum.

Currently ip6_input() calls in6ifa_ifwithaddr() for
every local packet, in order to check if the target ip
belongs to the local ifa in proper state and increase
its counters.
in6ifa_ifwithaddr() references found ifa.
With epoch changes, both `ip6_input()` and all other current callers
of `in6ifa_ifwithaddr()` do not need this reference
anymore, as epoch provides stability guarantee.
Given that, update `in6ifa_ifwithaddr()` to allow
it to return ifa without referencing it, while preserving
option for getting referenced ifa if so desired.

Currently the struct has a 4 byte padding stemming from 3 ints.
1. prio comfortably fits in short, unfortunately there is no dedicated
type for it and plumbing it throughout the codebase is not worth it
right now, instead an assert is added which covers also flags for
safety
2. lk_exslpfail can in principle exceed u_short, but the count is
already not considered reliable and it only ever gets modified
straight to 0. In other words it can be incrementing with an upper
bound of USHRT_MAX
With these in place struct lock shrinks from 48 to 40 bytes.

From openzfs-master 62d4287f2 commit message:
When scrubbing, (non-sequential) resilvering, or correcting a checksum
error using RAIDZ parity, ZFS should heal any incorrect RAIDZ parity by
overwriting it. For example, if P disks are silently corrupted (P being
the number of failures tolerated; e.g. RAIDZ2 has P=2), `zpool scrub`
should detect and heal all the bad state on these disks, including
parity. This way if there is a subsequent failure we are fully
protected.
With RAIDZ2 or RAIDZ3, a block can have silent damage to a parity
sector, and also damage (silent or known) to a data sector. In this
case the parity should be healed but it is not.
