Modified Files: src/sys/kern: kern_lock.c Log Message: ASSERT_SLEEPABLE(9): Micro-optimize this a little bit. This convinces gcc to do less -- make a smaller stack frame, compute fewer conditional moves in favour of predicted-not-taken branches -- in the fast path where we are sleepable as the caller expects. Wasn't able to convince it to do the ncsw loop with a predicted-not-taken branch, but let's leave the __predict_false in there anyway because it's still a good prediction.
