Modified files:
sys/sys proc.h umtx.h
sys/kern kern_umtx.c
Log:
- Remove the blocked pointer from the umtx structure.
- Use a hash of umtx queues to queue blocked threads. We hash on pid and the
virtual address of the umtx structure. This eliminates cases where we
previously held a lock across a casuptr call.
