[PATCH] Fix memory ordering problem in wake_futex()
Fix a memory ordering problem that occurs on IA64. The "store" to q->lock_ptr in wake_futex() can become visible before wake_up_all() clears the lock in the futex_q. Signed-off-by: Jack Steiner <steiner@sgi.com> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
