UPDATING sys/conf options sys/kern kern_lock.c kern_mutex.c kern_rwlock.c kern_sx.c subr_lock.c subr_witness.c sys/sys _lock.h _mutex.h lock.h lockmgr.h mutex.h sys/sun4v/include cpufunc.h Added files: sys/sys lock_profile.h Log: MUTEX_PROFILING has been generalized to LOCK_PROFILING. We now profile wait (time waited to acquire) and hold times for *all* kernel locks. If the architecture has a system synchronized TSC, the profiling code will use that - thereby minimizing profiling overhead. Large chunks of profiling code have been moved out of line, the overhead measured on the T1 for when it is compiled in but not enabled is < 1%.
