This patch series adds sas_ncq_prio_supported and sas_ncq_prio_enable sysfs sttributes for libsas managed SATA devices. Existing libata sysfs attributes cannot be used directly because the ata_port location is different for libsas. Changes since v4: - Updated sas_ncq_prio_* sysfs functions to use WARN_ON_ONCE() instead of WARN_ON(). Changes since v3: - Changed ata_ncq_prio_supported() and ata_ncq_prio_enabled() to store the result into a boolean variable passed by address. - Removed the "usable with both libsas and libata" wording from ata_ncq_prio_* helper's function comments. - Removed the unlikely() in ata_ncq_prio_enable() because the function is not in a fastpath. - Dropped hisi_sas v1 HW driver changes because it doesn't support SATA. Changes since v2: - Added libsas SATA sysfs attributes to aic94xx and isci. Changes since v1: - Dropped the "sas_" prefix to align sysfs sttributes naming with AHCI. - Dropped ternary operators to make the code more readable. - Corrected the formatting %u -> %d in sysfs_emit(). - Changed kstrtol() to kstrtobool() in [ata|sas]_ncq_prio_enable_store(). - Changed comments to use the "/* */" style instead of "//". - Added libsas SATA sysfs attributes to mvsas and hisi_sas. - Dropped the 'Reviewed-by' tags because they were not sent in-reply to the patch emails.
