From: nagalakshmi.nandigama@lsi.com Date: Thu, 1 Dec 2011 02:22:56 +0000 (+0530) Subject: SCSI: mpt2sas: Release spinlock for the raid device list before blocking it X-Git-Tag: v3.2.2~94 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7af050182f68de53d4c323367c793c580e956041;p=pandora-kernel.git SCSI: mpt2sas: Release spinlock for the raid device list before blocking it commit 30c43282f3d347f47f9e05199d2b14f56f3f2837 upstream. Added code to release the spinlock that is used to protect the raid device list before calling a function that can block. The blocking was causing a reschedule, and subsequently it is tried to acquire the same lock, resulting in a panic (NMI Watchdog detecting a CPU lockup).
