4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Naoya Horiguchi <[email protected]> [ Upstream commit 904506562e0856f2535d876407d087c9459d345b ] Currently we get the following compiler warning: slabinfo.c:854:22: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] if (s->object_size < min_objsize) ^ due to the mismatch of signed/unsigned comparison. ->object_size and ->slab_size are never expected to be negative, so let's define them as unsigned int.
