From 7c9adf5a5471647f392169ef19d3e81dcfa76045 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 4 Sep 2012 23:38:33 +0000 Subject: mm/sl[aou]b: Move list_add() to slab_common.c Move the code to append the new kmem_cache to the list of slab caches to the kmem_cache_create code in the shared code. This is possible now since the acquisition of the mutex was moved into kmem_cache_create().
