[PATCH 4.18 071/168] tools/vm/slabinfo.c: fix sign-compare warning

[Greg Kroah-Hartman]

4.18-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]
