src/sys/sys: lwp.h sleepq.h
Log Message:
- Fix a few possible locking issues in execve1() and exit1(). Add a note
that scheduler locks are special in this regard - adaptive locks cannot
be in the path due to turnstiles. Randomly spotted/reported by uebay...@.
- Remove unused lwp_relock() and replace lwp_lock_retry() by simplifying
lwp_lock() and sleepq_enter() a little.
- Give alllwp its own cache-line and mark lwp_cache pointer as read-mostly.
