From 84f95243b5439a20c33837075b88926bfa00c4ec Mon Sep 17 00:00:00 2001 From: Adam Manzanares Date: Mon, 17 Oct 2016 11:27:30 -0700 Subject: ata: ATA Command Priority Disabled By Default Add a sysfs entry to turn on priority information being passed to a ATA device. By default this feature is turned off. This patch depends on ata: Enabling ATA Command Priorities tj: Renamed ncq_prio_on to ncq_prio_enable and removed trivial ata_ncq_prio_on() and open-coded the test.
