From fea1b139735355fe17a66f63811c58698ff03ec5 Mon Sep 17 00:00:00 2001 From: Ed Cashin Date: Wed, 11 Sep 2013 14:25:46 -0700 Subject: [PATCH] aoe: do not BUG if memory pressure prevented debugfs file creation If the system has trouble allocating memory for the creation of the aoe debugfs directory or of a file inside it, the debugfs member of an aoedev can be NULL. Do not treat a NULL debugfs pointer as a BUG on aoedev shutdown, avoiding the user impact of an unecessary panic.
