Use file name hash as a tree key, handle duplicate keys. Both VOP_LOOKUP
and VOP_READDIR operations utilize same tree for search. Directory
entry offset (cookie) is either file name hash or incremental id in case
of hash collisions (duplicate-cookies). Keep sorted per directory list
of duplicate-cookie entries to facilitate cookie number allocation.
Don't fail if previous VOP_READDIR() offset is no longer valid, start
with next dirent instead. Other file system handle it similarly.
Workaround race prone tn_readdir_last[pn] fields update.
Add tmpfs_dir_destroy() to free all dirents.
Set NFS cookies in tmpfs_dir_getdents(). Return EJUSTRETURN from
tmpfs_dir_getdents() instead of hard coded -1.
Mark directory traversal routines static as they are no longer
used outside of tmpfs_subr.c
* Mikrotik RouterBoard 433AH have PCI slot 18 wired to INT0 on the PCI Bus.
This is different from e.g. Atheros PB42 and Ubiquiti boards.
* Check for hint hint.pcib.0.baseslot=X, where X is number of base slot;
* If hint not supplied print a warning and use default AR71XX_PCI_BASE_SLOT;

This is a horrible hack to get freefall to compile, and is in dire need
of reconciliation. This antique zlib-1.04 code needs to go away.
If the data frame transmission failures, it may have a node reference
that needs cleaning up.
If the frame is marked as M_ENCAP then it should treat recvif as a node
reference and clear it.
Now - since the mbuf has been freed by calling if_transmit() (even on
failure), the mbuf has to be treated as invalid. Hence why the ifp is
used.
If if_transmit() fails, the node ref may need freeing.
This is based on the same logic used by the ageq, which the mesh code
(re) uses for frames which need to be staged before transmitting.
It also does the same thing - if M_ENCAP is set on the mbuf, it treats
the recvif pointer as a node reference and derefs it.
when comparing its size with the size of the media, to determine if
the last disk block is unused.

time to evaluate the effectiveness of different
watchdog strategies.
This is the latest attempt, which consolidates
all of the watchdog logic in one place and
consistently detects TX stalls and resets within
a couple of seconds.

the free nullfs vnodes, switching nullfs behaviour to pre-r240285.
The option is mostly intended as the last-resort when higher pressure
on the vnode cache due to doubling of the vnode counts is not
desirable.
Note that disabling the cache costs more than 2x wall time in the
metadata-hungry scenarious. The default is "cache".
