Modified files:
sys/kern kern_rwlock.c
Log:
- Add a rw_wowner() macro that just returns the owner of a write lock and
use it in places that only care about the write owner instead of
rw_owner() as a baby step towards limited read-lock owner.
- Tidy the code that sets the WAITER flag bits to not duplicate a test
around the atomic operation and the KTR trace in both of the lock
functions.
