jhb 2001/06/22 16:11:26 PDT Modified files: sys/kern kern_synch.c Log: - Lock CURSIG() with the proc lock to close the signal race with psignal. - Grab Giant around ktrace points. - Clean up KTR_PROC tracepoints to not display the value of sched_lock.mtx_lock as it isn't really needed anymore and just obfuscates the messages. - Add a few if conditions to replace gotos. - Ensure that every msleep KTR event ends up with a matching msleep resume KTR event (this was broken when we didn't do a mi_switch()). - Only note via ktrace that we resumed from a switch once rather than twice in several places in msleep(). - Remove spl's rom asleep and await as the proc lock and sched_lock provide all the needed locking. - In mawait() add in a needed ktrace point for noting that we are about to switch out.
