Petersen" <martin.petersen@...cle.com>, Tejun Heo <tj@...nel.org>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.19.y-ckt 035/146] libata: Blacklist queued TRIM on all Samsung 800-series 3.19.8-ckt2 -stable review patch. If anyone has any objections, please let me know. ------------------ From: "Martin K. Petersen" <martin.petersen@...cle.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.
