From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx> Date: Fri, 27 Mar 2015 15:17:20 -0400 commit ff7f53fb82a7801a778e5902bdbbc5e195ab0de0 upstream. Micron has released an updated firmware (MU02) for M510/M550/MX100 drives to fix the issues with queued TRIM. Queued TRIM remains broken on M500 but is working fine on later drives such as M600 and MX200. Tweak our blacklist to reflect the above.
