[PATCH] lockdep: rename DEBUG_WARN_ON()
Rename DEBUG_WARN_ON() to the less generic DEBUG_LOCKS_WARN_ON() name, so that it's clear that this is a lock-debugging internal mechanism. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
