[PATCH 3.13 160/160] libata: Blacklist queued trim for Crucial M500

From: Kamal Mostafa
Date: Tue Jun 10 2014 - 16:02:47 EST


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

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

From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx>

commit 3b8d2676d15d6b2326757adb66b70a9cd6650373 upstream.

Queued trim only works for some users with MU05 firmware. Revert to
blacklisting all firmware versions.

Introduced by commit d121f7d0cbb8 ("libata: Update queued trim blacklist
for M5x0 drives") which this effectively reverts, while retaining the
blacklisting of M550.

See

https://bugzilla.kernel.org/show_bug.cgi?id=71371

for reports of trouble with MU05 firmware.
