    sys/net              pfil.c pfil.h 
  Log:
  pfil(9) locking take 3:  Switch to rmlock(9)
  This has the benefit that rmlocks have proper support for reader recursion
  (in contrast to rwlock(9) which could potential lead to writer stravation).
  It also means a significant performance gain, eventhough only visible in
  microbenchmarks at the moment.
