From: James Bottomley
Date: Fri Aug 21 2009 - 21:29:15 EST
This represents a set of bugfixes for the new mpt2sas driver only.
The patch is available from:
master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git
The short changelog is
Kashyap, Desai (9):
mpt2sas: fix config request and diag reset deadlock
mpt2sas: Bump driver version 01.100.04.00
mpt2sas: fix oops because drv data points to NULL on resume from hibernate
mpt2sas: fix crash due to Watchdog is active while OS in standby mode
mpt2sas: fix infinite loop inside config request
mpt2sas: Excessive log info causes sas iounit page time out
mpt2sas: Raid 10 Value is showing as Raid 1E in /va/log/messages
mpt2sas: Expander fix oops saying "Already part of another port"
mpt2sas: Introduced check for enclosure_handle to avoid crash
