FreeBSD src repository
Modified files:
sys/kern kern_rwlock.c
sys/sys rwlock.h
Log:
Add rw_try_rlock() and rw_try_wlock() to rwlocks.
These functions try the specified operation (rlocking and wlocking) and
true is returned if the operation completes, false otherwise.
The KPI is enriched by this commit, so __FreeBSD_version bumping and
manpage updating will happen soon.
