This change was originally intended to account for test kthreads under
the nvmecontrol process, but jhb indicated it may not be safe to
associate kthreads with userland processes and this could have
unintended consequences.
I did not observe any problems with this change, but my testing didn't
exhaust the kinds of corner cases that could cause problems. It is not
that important to account for these test threads under nvmecontrol, so I
am just reverting this change for now.
On a related note, the part of this patch for <= 7.x fails compilation
so reverting this fixes that too.

Preloaded library could have changed the environment, and
unconditional assingment to the environ undoes the customization.
The binaries needs to be recompiled to get the fix.
Move the common code to set up environ and __progname into the helper.
Note that ia64 possibly not fixed, due to it still using old csu.

This patch will save CPU time when the XHCI interrupt is
shared with other devices.
Only check event rings when interrupt bits are set.
Otherwise would indicate hiding possible hardware fault(s).

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Don't fail if previous VOP_READDIR() offset is no longer valid, start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.

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.

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.
