nvme: new define for size of host memory buffer sizes
The nvme spec defines the various fields that specify sizes for host
memory buffers in terms of 4096 chunks. So, rather than use a bare 4096
here, use NVME_HMB_UNITS. This is explicitly not the host page size of
4096, nor the default memory page size (mps) of the NVMe drive, but its
own thing and needs its own define.
No functional change is intended, only the logical spelling of 4k.

Speed up *-old-* make targets by using sed instead of xargs
Targets like 'list-old-files' used "xargs -n1" to produce a list with
one file per line. Using xargs resulted in one fork+exec for each
Argument, resulting in rather long runtime. Instead, use sed to split
the list. On one machine `make list-old-files` took 30s wall clock time
with xargs and less than 1s with sed.

pf: Workaround set but unused warning.
The RB_NEXT macro does not use its middle argument since commit 5fce408cc44c737267aaaf0dcecd3454ba9089cd 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.

nfscl: Add support for a NFSv4 AppendWrite RPC
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
roundup2().

ffs: wait for trims earlier during unmount to avoid panic
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.

net: Fix memory leaks in lltable_calc_llheader() error paths
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.

net: Fix LLE lock leaks
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.
