mm/slub.c: clean up validate_slab()
The function doesn't need to return any value, and the check can be done in one pass. There is a behavior change: before the patch, we stop at the first invalid free object; after the patch, we stop at the first invalid object, free or in use. This shouldn't matter because the original behavior isn't intended anyway. Link: http://lkml.kernel.org/r/20191108193958.205102-1-yuzhao@google.com Signed-off-by:Yu Zhao <yuzhao@google.com> Acked-by:
