sys/kern kern_lock.c subr_witness.c
Log:
- Re-introduce WITNESS support for lockmgr. About the old implementation
the only one difference is that lockmgr*() functions now accept
LK_NOWITNESS flag which skips ordering for the instanced calling.
- Remove an unuseful stub in witness_checkorder() (because the above check
doesn't allow ever happening) and allow witness_upgrade() to accept
non-try operation too.
