[PATCH 02/17] futex: Use smp_store_release() in mark_wake_futex()

From: Peter Zijlstra commit 1b367ece0d7e696cab1c8501bab282cc6a538b3f upstream. Since the futex_q can dissapear the instruction after assigning NULL, this really should be a RELEASE barrier. That stops loads from hitting dead memory too. Signed-off-by: Peter Zijlstra (Intel) Cc:
