Alexander V. Chernikov e4b3229aa5 - Improve BPF locking model. ... Interface locks and descriptor locks are converted from mutex(9) to rwlock(9). This greately improves performance: in most common case we need to acquire 1 reader lock instead of 2 mutexes. - Remove filter(descriptor) (reader) lock in bpf_mtap[2] This was suggested by glebius@. We protect filter by requesting interface writer lock on filter change. - Cover struct bpf_if under BPF_INTERNAL define. This permits including bpf.h without including rwlock stuff. However, this is is temporary solution, struct bpf_if should be made opaque for any external caller.
