[PATCH] fix/simplify mutex debugging code
Let's switch mutex_debug_check_no_locks_freed() to take (addr, len) as arguments instead, since all its callers were just calculating the 'to' address for themselves anyway... (and sometimes doing so badly). Signed-off-by: David Woodhouse <dwmw2@infradead.org> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
