Modified files:
sys/kern subr_witness.c
Log:
- Don't panic on a try lock operation for a sleep lock if we hold a spin
lock. Since we won't actually block on a try lock operation, it's not
a problem. Add a comment explaining why it is safe to skip lock order
checking with try locks.
- Remove the ithread list lock spin lock from the order list.
