Subject: [PATCH 3/3] tools/vm/slabinfo: update struct slabinfo members' types
Date: Tue, 10 Nov 2015 22:32:06 +0900	[thread overview]
Message-ID: <1447162326-30626-4-git-send-email-sergey.senozhatsky@gmail.com> (raw)
In-Reply-To: <1447162326-30626-1-git-send-email-sergey.senozhatsky@gmail.com>

Align some of `struct slabinfo' members' types with
`struct kmem_cache' to suppress gcc warnings:

slabinfo.c:847:22: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
slabinfo.c:869:20: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
slabinfo.c:872:22: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
slabinfo.c:894:20: warning: comparison between signed
  and unsigned integer expressions [-Wsign-compare]
