Michael S. Tsirkin 406de75554 ptr_ring: keep consumer_head valid at all times ... The comment near __ptr_ring_peek says: * If ring is never resized, and if the pointer is merely * tested, there's no need to take the lock - see e.g. __ptr_ring_empty. but this was in fact never possible since consumer_head would sometimes point outside the ring. Refactor the code so that it's always pointing within a ring. Fixes: c5ad119fb6 ("net: sched: pfifo_fast use skb_array") Signed-off-by: Michael S.
