Sudip,
v1: Only M500IT MU01 was blacklisted.
v2: Whitelist M500IT BG02 and M500DC and then blacklist all other Micron.
I think my preference would be to blacklist M500IT with the MU01 firmware (which Micron said was affected) and rely on the "Micron*" fallthrough further down for the rest.
I have not gotten firm confirmation on ZRAT behavior so for now we should probably just do:
+ { "Micron_M500IT_*", "MU01", ATA_HORKAGE_NO_NCQ_TRIM, },
