[PATCH v1] tools/vm/slabinfo.c: fix sign-compare warning

From: Naoya Horiguchi
Date: Fri Aug 24 2018 - 05:32:32 EST


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.
