[PATCH] lockdep ifdef fix
With CONFIG_SMP=y CONFIG_PREEMPT=y CONFIG_LOCKDEP=y CONFIG_DEBUG_LOCK_ALLOC=y # CONFIG_PROVE_LOCKING is not set spin_unlock_irqrestore() goes through lockdep but spin_lock_irqsave() doesn't. Apparently, bad things happen. Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
