Modified files:
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.
Discussed on: -arch, -net
