[v2,0/5] NCQ Priority sysfs sttributes for libsas

Message

Igor Pylypiv March 2, 2024, 12:15 a.m. UTC

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 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.
