Subject: [PATCH v4 0/7] NCQ Priority sysfs sttributes for libsas
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 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.
