Couple of heads up if you are playing with the tmpfs diff from pedro.

NetBSD does the sanity checking for hardlinks (not across mountpoints, not
on directories)
at the syscall layer and KASSERTs this in the filesystems.

Also, lockstatus() needs to be able to report if the lock is exclusive or
shared
(for naked VOP_ISLOCKED() == LK_EXCLUSIVE) checks.

I've fixed both issues here:
