[PATCH 3.13.y-ckt 41/57] Add factory recertified Crucial M500s to blacklist

From: Kamal Mostafa
Date: Tue Sep 22 2015 - 15:05:31 EST


3.13.11-ckt27 -stable review patch. If anyone has any objections, please let me know.

------------------

From: "Guillermo A. Amaral" <g@xxxxxxxx>

commit 7a7184b01aa9deb86df661c6f7cbcf69a95b728c upstream.

The Crucial M500 is known to have issues with queued TRIM commands, the
factory recertified SSDs use a different model number naming convention
which causes them to get ignored by the blacklist.

The new naming convention boils down to: s/Crucial_/FC/

[ luis: backported to 3.16:

- adjusted context ]
