Modified files:
sys/kern subr_witness.c
Log:
- 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.
