Subject: [PATCH 4.4 014/124] mm/slub.c: add __printf verification to slab_err()
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathieu Malaterre <malat@...ian.org>
[ Upstream commit a38965bf941b7c2af50de09c96bc5f03e136caef ]
__printf is useful to verify format and arguments. Remove the following
warning (with W=1):
mm/slub.c:721:2: warning: function might be possible candidate for `gnu_printf' format attribute [-Wsuggest-attribute=format]
