From 5cbf015b971c8bf9bb9b6796dc92d78b51bc62b5 Mon Sep 17 00:00:00 2001 From: Naoya Horiguchi Date: Tue, 4 Sep 2018 15:45:48 -0700 Subject: tools/vm/slabinfo.c: fix sign-compare warning [ 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.
