Subject: [PATCH] libata: Enable queued TRIM for Samsung SSD 860
Patch-mainline: v4.16-rc7
Git-commit: ca6bfcb2f6d9deab3924bf901e73622a94900473
References: bsc#1077989
Samsung explicitly states that queued TRIM is supported for Linux with
860 PRO and 860 EVO.
Make the previous blacklist to cover only 840 and 850 series.
