From c9cd3504eb03755db8e64f894ccd4ebee59734b7 Mon Sep 17 00:00:00 2001 From: Tom Yan Date: Wed, 13 Jul 2016 02:54:11 +0800 Subject: [PATCH] libata-scsi: fix D_SENSE bit relection in control mode page The bit should always be set to 1 when the requested version of page is "changeable" because we've made it so in ata_mselect_control(). Also, it should always be set to 1 if ATA_DFLAG_D_SENSE is set (when the requested version of page is "current" or "default").
