tools/vm/slabinfo.c: fix sign-compare warning
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] Link: http://lkml.kernel.org/r/20180826234947.GA9787@hori1.linux.bs1.fc.nec.co.jp Link: http://lkml.kernel.org/r/1535103134-20239-1-git-send-email-n-horiguchi@ah.jp.nec.com Signed-off-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Cc: Matthew Wilcox <willy@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
