    Subject[PATCH 3.19.y-ckt 078/102] Add factory recertified Crucial M500s to blacklist
    Date
    3.19.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

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

    From: "Guillermo A. Amaral" <g@maral.me>

    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/
