  Modified files:
    sys/kern             kern_rwlock.c 
  - 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
