From 0c12735e8abf4734b011aec979092db5e63556b0 Mon Sep 17 00:00:00 2001 From: Tom Yan Date: Tue, 12 Jul 2016 21:37:02 +0800 Subject: libata-scsi: fix SET FEATURES "filtering" for ata_msense_caching() Without this fix, the DRA bit of the caching mode page would not be updated when the read look-ahead feature is toggled (e.g. with `smartctl --set`), but will only be until, for example, the write cache feature is touched.
