From eefaca9c3246f3daf56e7ed02987f79abcee7087 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 16 May 2007 22:10:55 -0700 Subject: [PATCH] SLUB: slabinfo fixes Align the output of % with K/M/G of sizes. Check for empty NUMA information to avoid segfault on !NUMA. -r should work directly not only if we match a single slab without additional options.
