From: "Martin K. Petersen" <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== 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.
