From e85fbc595aa527e0b3c9a738c4dc1d7717afb30c Mon Sep 17 00:00:00 2001 From: "Salyzyn, Mark" Date: Wed, 31 Oct 2007 16:40:37 -0400 Subject: [PATCH] [SCSI] aacraid: fix potential panic in thread stop Got a panic in the threading code on an older kernel when the Adapter failed to load properly and driver shut down apparently before any threading had started, can not dupe. Expect that this may be relevant in the latest kernel, but not sure. This patch does no harm, and should alleviate the possibility of this panic.
