From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Wed, 22 Aug 2007 15:14:49 -0700 (PDT) From: Christoph Lameter Subject: [PATCH] Do not fail if we cannot register a slab with sysfs Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: akpm@linux-foundation.org Cc: linux-mm@kvack.org, davem@davemloft.net List-ID: Do not BUG() if we cannot register a slab with sysfs. Just print an error. The only consequence of not registering is that the slab cache is not visible via /sys/slab. A BUG() may not be visible that early during boot and we have had multiple issues here already.
