[PATCH 3.19.y-ckt 078/102] Add factory recertified Crucial M500s to blacklist

From: Kamal Mostafa
Date: Tue Sep 22 2015 - 14:06:25 EST


3.19.8-ckt7 -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/
