The RB_NEXT macro does not use its middle argument since commit
5fce408cc4 in 2004 (which ironically
fixed an "unused parameter" warning by introducing this warning in all
consumers). RB_PREV has also copied this unfortunate behavior of an
unused argument.
This results in 'parent' not being used. To workaround, inline the
value of 'parent' as the second argument to RB_NEXT.

For IO_APPEND VOP_WRITE()s, the code first does a
Getattr RPC to acquire the file's size, before it
can do the Write RPC.
Although NFS does not have an append write operation,
an NFSv4 compound can use a Verify operation to check
that the client's notion of the file's size is
correct, followed by the Write operation.
This patch modifies nfscl_wcc_data() to optionally
acquire the file's size, for use with an AppendWrite.
Although the "stuff" arguments are always NULL
(these were used for the Mac OSX port and should be
cleared out someday), make the argument to
nfscl_wcc_data() explicitly NULL for clarity.
This patch does not cause any semantics change until
the AppendWrite is added in a future commit.
Add ALIGN_DOWN as rounddown2() along ALIGN() which is implemented as

All softdep processing is supposed to be completed by
softdep_flushfiles() and no more deps are supposed to be created after
that, but if a pending trim completes after softdep_flushfiles() and
before softdep_unmount() then the blkfree that is performed by
ffs_blkfree_trim_task() will create a dep when none should exist, and
if softdep_unmount() is called before that dep is freed then the
kernel will panic. Prevent this by waiting for trims to complete
earlier in the unmount process, in ffs_flushfiles(), so that any deps
will be freed and any modified CG buffers will be flushed by the final
fsync of the devvp in ffs_flushfiles() as intended.

Also convert raw epoch_call() calls to lltable_free_entry() calls, no
functional change intended. There's no need to asynchronously free the
LLEs in that case to begin with, but we might as well use the lltable
interfaces consistently.
Noticed by code inspection; I believe lltable_calc_llheader() failures
do not generally happen in practice.

Historically, lltable_try_set_entry_addr() would release the LLE lock
upon failure. After some refactoring, it no longer does so, but
consumers were not adjusted accordingly.
Also fix a leak that can occur if lltable_calc_llheader() fails in the
ARP code, but I suspect that such a failure can only occur due to a code
bug.

60970a328e did one half of the job
of making rssi relative to nf and numbers for radiotap were fine.
net80211 internally works with .5 dBm units thus we need to apply a
* 2 to the value we pass in to c_rssi; leave a comment explaining.
Note: it is only ifconfig in user space which re-adjust it for printing
or contrib/wpa for calculations. Other applications getting values
from kernel also have to apply the maths.

FSE_createCTable raises the warning because we stub out malloc() to
NULL in the kernel, so the passed in size is unused.
ZSTD_seqDecompressedSize has a variable whose value is only used in
assertions.
NB: These files are missing corresponding entries in sys/conf/files.
All of the legacy config stuff in tpm seems broken. Nothing ever sets
tpm_enabled to a non-zero value and the legacy bits expect tpm_enabled
to be set to the base IO port address (I think).
The Linux driver clears ATI_REG_CMD_AC_RESET and sets
ATI_REG_CMD_POWERDOWN, so writing the calculated value that sets both
would seem to be wrong. This could be updated to match Linux's
behavior, but instead I've just left it as-is.
Both rwlwifi in Linux and rtwn in OpenBSD restore this register,
and the existing code was saving the value and not using it.
