Quick kill links to the nsmb(8) manual page, there is no such
utility that I can find.
| There is no need to explicitly add "status" to $extra_commands in
| the /etc/rc.d/pf script as it is implicitly added by /etc/rc.subr's
| run_rc_command() because of the existing $pf_program.

Teach vmstat's domemstat_zone() to use memstat_kvm_uma() when the kvm
descriptor is non-NULL, restoring vmstat -z support for core dumps and
kmem access. These were broken with the introduction of UMA.
memstat_malloc:1.6 from HEAD to RELENG_6:
Teach libmemstat(3) how to extract malloc(9) statistics using kvm(3),
so that libmemstat can be used to view full memory statistics from
kernel core dumps and /dev/mem. This is provided via a new query
function, memstat_kvm_malloc(), which is also automatically invoked
by memstat_kvm_all(). A kvm handle must be passed in.
This will allow malloc(9)-specific code to be removed from vmstat(8).
memstat_uma.c:1.10 from HEAD to RELENG_6:
Add memstat_kvm_uma(), an implementation of a libmemstat(3) query routine
that knows how to extract UMA(9) allocator statistics from a core dump or
live memory image using kvm(3). The caller is expected to provide the
necessary kvm_t handle, which is then used by libmemstat(3).
With these changes, it is trivially straight forward to re-introduce
vmstat -z support on core dumps, which was lost when UMA was introduced.
In the short term, this requires including vm/ include files that are not
intended for extra-kernel use, requiring in turn some ugliness.
Merge memstat_uma.c:1.11 from HEAD to RELENG_6:
Define LIBMEMSTAT so that vm_page.h won't perform a nested include of
opt_vmpage.h.
Remove definition of _KERNEL, it is no longer required in order to
include uma_int.h, as the sensitive parts of uma_int.h (a number of
inlines depending on kernel-only constants) are now protected by
_KERNEL.
The use of LIBMEMSTAT here will be cleaned up in the future.
- Use if_printf() and device_printf() and remove vr_unit from the softc.
I had to initialize the ifnet a bit earlier in attach so that the
if_printf()'s in vr_reset() didn't explode with a page fault.
- Use M_ZERO with contigmalloc() rather than an explicit bzero.
- Use callout_*() to manage the callout and make it MPSAFE.
- Fix locking in detach(), we only need to lock across vr_stop().
is an instant MFC as it was actually tested on 5.x and 6.x. Note that like
the change to HEAD, this renames the devices, and there is no easy way on
6.x to create compatibility names in the kernel.

Add a "show malloc" command to DDB, which prints out the current stats for
available kernel malloc types. Quite useful for post-mortem debugging of
memory leaks without a dump device configured on a panicked box.
Add a "show uma" command to DDB, which prints out the current stats for

- Support for command -v and -V.
- Fixes for the errexit option.
- A fix for a crash caused by SIGINT.
- POSIX compliant set +o ouput.
- A fix for unalias' exit code.
- Man page updates.
- Code cleanups, WARNS 3.
- Enforce an implicit lock order that Giant cannot be locked while holding
any other non-sleepable lock. In plain English: Giant comes before all
other mutexes.
- Add some extra description to the lock order reversal printf's to indicate
when a reversal is triggered by a hard-coded implicit rule.
