Subject: [PATCH AUTOSEL 4.14 35/36] tools/vm/slabinfo.c: fix sign-compare warning
Date: Mon, 24 Sep 2018 14:49:12 +0000	[thread overview]
Message-ID: <20180924144851.164533-35-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180924144851.164533-1-alexander.levin@microsoft.com>

From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>

[ 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@ah.jp.nec.com: convert everything - none of these can be negative]
