tcp: tsq: remove one locked operation in tcp_wfree() Instead of atomically clear TSQ_THROTTLED and atomically set TSQ_QUEUED bits, use one cmpxchg() to perform a single locked operation. Since the following patch will also set TCP_TSQ_DEFERRED here, this cmpxchg() will make this addition free. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
