Willem de Bruijn a6361f0ca4 packet: fix bitfield update race ... Updates to the bitfields in struct packet_sock are not atomic. Serialize these read-modify-write cycles. Move po->running into a separate variable. Its writes are protected by po->bind_lock (except for one startup case at packet_create). Also replace a textual precondition warning with lockdep annotation. All others are set only in packet_setsockopt. Serialize these updates by holding the socket lock. Analogous to other field updates, also hold the lock when testing whether a ring is active (pg_vec).
