Subject[PATCH 4.14 013/496] libata: Blacklist some Sandisk SSDs for NCQ
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Tejun Heo <tj@kernel.org>

commit 322579dcc865b94b47345ad1b6002ad167f85405 upstream.

Sandisk SSDs SD7SN6S256G and SD8SN8U256G are regularly locking up
regularly under sustained moderate load with NCQ enabled. Blacklist
for now.
