change the mbuf pointer and we don't have any way of passing
it back to the callers. Instead just fail silently without
updating the checksum but leaving the mbuf+chain intact.
A search in our GNATS database did not turn up any match for
the existing warning message when this case is encountered.

The change I made against the original patch is to fall back to the given
path on realpath(2) failure instead of exiting with an error.

So we can keep statistic across ifconfig down/up runs (cause bringing
bge up will reset chip).

equal to NULL several times later. p_ucred "should probably not" be NULL
if the process isn't PRS_NEW anyway. This is strongly reinforced by the fact
that we don't see frequent crashes here. Remove the checks after p_cansee and
add a KASSERT right before it.

last few days. I tracked it down to the fact that nfs_reclaim()
is setting vp->v_data to NULL _before_ calling vnode_destroy_object().
After silence from the mailing list I checked further and discovered
that ufs_reclaim() is unique among FreeBSD filesystems for calling
vnode_destroy_object() early, long before tossing v_data or much
of anything else, for that matter. The rest, including NFS, appear
to be identical, as if they were just clones of one original routine.
The enclosed patch fixes all file systems in essentially the same
way, by moving the call to vnode_destroy_object() to early in the
routine (before the call to vfs_hash_remove(), if any). I have
only tested NFS, but I've now run for over eighteen hours with the
patch where I wouldn't get past four or five without it.

lock_obj objects:
- Add new lock_init() and lock_destroy() functions to setup and teardown
lock_object objects including KTR logging and registering with WITNESS.
- Move all the handling of LO_INITIALIZED out of witness and the various
lock init functions into lock_init() and lock_destroy().
- Remove the constants for static indices into the lock_classes[] array
and change the code outside of subr_lock.c to use LOCK_CLASS to compare
against a known lock class.
- Move the 'show lock' ddb function and lock_classes[] array out of
kern_mutex.c over to subr_lock.c.
