Date: Thu Mar 20 2014 - 21:14:31 EST

3.13-stable review patch. If anyone has any objections, please let me know.


From: Marios Andreopoulos <opensource@xxxxxxxxxxxxx>

commit 2564338b13e6e132ee224edb63e1e872adf431f4 upstream.

Queued TRIM commands cause problems and silent file system corruption
on Crucial M500 SSDs. This patch disables them for the mSATA model of
the drive.
