From ec1f5eeeb5a79a0d48036de649a3498da42db565 Mon Sep 17 00:00:00 2001 From: Daniel Yeisley Date: Tue, 25 Mar 2008 23:59:08 +0200 Subject: [PATCH] slab: fix cache_cache bootstrap in kmem_cache_init() Commit 556a169dab38b5100df6f4a45b655dddd3db94c1 ("slab: fix bootstrap on memoryless node") introduced bootstrap-time cache_cache list3s for all nodes but forgot that initkmem_list3 needs to be accessed by [somevalue + node]. This patch fixes list_add() corruption in mm/slab.c seen on the ES7000.
