3.16.7-ckt13 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: "Martin K. Petersen" <martin.peter...@oracle.com>
commit 9a9324d3969678d44b330e1230ad2c8ae67acf81 upstream.
The queued TRIM problems appear to be generic to Samsung's firmware and
not tied to a particular model. A recent update to the 840 EVO firmware
introduced the same issue as we saw on 850 Pro.
Blacklist queued TRIM on all 800-series drives while we work this issue
with Samsung.
