Comment here already says it isn't necessary and will be removed.
Hasten the process for us and avoid the problematic typedef.
This is useful because u_longlong_t would otherwise need to be
provided by compat headers.
Mark arguments to dtrace_probe_lookup() with __UNCONST().
The proper fix constifying it causes pollution of const in too many files.
This could be done with -W flags, but they are incompatible between
compilers.

Add missing const keywords in dtrace_strncmp().
Initialize lim1 and lim2 to zero always. This prevents a false positive
about potentially unset but used variable.

merge a new version of the CDDL dtrace and ZFS code.
this changes the upstream vendor from OpenSolaris to FreeBSD,
and this version is based on FreeBSD svn r315983.
in addition to the 10 years of improvements from upstream,
this version also has these NetBSD-specific enhancements:
- dtrace FBT probes can now be placed in kernel modules.
- ZFS now supports mmap().

The following scripts are installed:
dtruss - a DTrace version of truss.
execsnoop - snoop process execution as it occurs.
opensnoop - snoop file opens as they occur.
procsystime - print process system call time details.

While it fixed the problem of trailing spaces, but if the probe specifier
contained leading spaces, it would brake dtrace. The proper fix would be
to skip the leading spaces in the string as well.
However, it would result in a bigger diff for a very small benefit. While
a new import of dtrace is impending, it's better not to have this change.
Discussed with christos.
When using dtrace using one of the tracing options, such as -n, -P, -i, -f etc.,
the first line of output from dtrace one is something like this:
sudo dtrace -n 'syscall:::entry /pid == 100/ {@num[probefunc] = count();}'
dtrace: description 'syscall:::entry ' matched 482 probes
There is a trailing space at the end of the probe specifier name ('syscall:::entry ').
This happens beucase dtrace tries to separate the probe name from the predicate and actions
using `{' and `/' as the separators but doesn't consider space also as a possible separator.
Output after this change:
sudo dtrace -n 'syscall:::entry /pid == 100/ {@num[probefunc] = count();}'
dtrace: description 'syscall:::entry' matched 482 probes

VOP_RECLAIM naturally has exclusive access to the vnode, so having it
locked on entry is not strictly necessary -- but it means if there
are any final operations that must be done on the vnode, such as
ffs_update, requiring exclusive access to it, we can now kassert that
the vnode is locked in those operations.
We can't just have the caller release the last lock because some file
systems don't use genfs_lock, and require the vnode to remain valid
for VOP_UNLOCK to work, notably unionfs.
fix the dtrace "args" variable to return correct values.
simplify the invop handlers a bit by changing the second argument
from a pointer into the stack to a pointer to the trapframe.
