sys/sys lock_profile.h mutex.h rwlock.h
sys/kern kern_lock.c kern_mutex.c kern_rwlock.c
kern_sx.c sched_ule.c subr_lock.c
Log:
general LOCK_PROFILING cleanup
- only collect timestamps when a lock is contested - this reduces the overhead
of collecting profiles from 20x to 5x
- remove unused function from subr_lock.c
- generalize cnt_hold and cnt_lock statistics to be kept for all locks
- NOTE: rwlock profiling generates invalid statistics (and most likely always
has)
someone familiar with that should review
