Subject: [PATCH v4 00/10] libata cleanups and improvements
Date: Sat, 7 Aug 2021 13:18:49 +0900 [thread overview]
Message-ID: <20210807041859.579409-1-damien.lemoal@wdc.com> (raw)
The first three patches of this series fix sparse and kernel bot
warnings (potential NULL pointer dereference and locking imbalance).
The following three patches cleanup libata-core code in the area of
device configuration (ata_dev_configure() function).
Patch 7 improves ata_read_log_page() to avoid unnecessary warning
messages and patch 8 adds an informational message on device scan to
advertize the features supported by a device.
Path 9 adds the new sysfs ahci device attribute ncq_prio_supported to
indicate that a disk supports NCQ priority. Patch 10 does the same for
the mpt3sas driver, adding the sas_ncq_prio_supported device attribute.
Changes from v3:
* Reworked patch 1
* Added patch 3 to fix a sparse warning discovered while checking
patch 1 & 2
* Added reviewed-by tags
Changes from v2:
* Reworked patch 4 to avoid the need for an additional on-stack string
for device information messages
* Added reviewed-by tags
Changes from v1:
* Added patch 1 and 2 to fix problems reported by the kernel test robot
* Use strscpy() instead of strcpy in patch 4
* Use sysfs_emit in patch 8 and 9 as suggested by Bart
* Fix typos in comments of the new sas_ncq_prio_supported attribute in
patch 9
