3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Naoya Horiguchi <n-horiguchi@xxxxxxxxxxxxx>
[ 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.
[n-horiguchi@xxxxxxxxxxxxx: convert everything - none of these can be negative]
