From b4d3ddd2df7531e35c5f4e0b048d0999851747ae Mon Sep 17 00:00:00 2001 From: Igor Pylypiv Date: Thu, 7 Mar 2024 13:44:13 -0800 Subject: scsi: libsas: Define NCQ Priority sysfs attributes for SATA devices libata sysfs attributes cannot be used for libsas-managed SATA devices because the ata_port location is different for libsas. Defined sysfs attributes (visible for SATA devices only): - /sys/block/sda/device/ncq_prio_enable - /sys/block/sda/device/ncq_prio_supported The newly defined attributes will pass the correct ata_port to libata helper functions.
