Subject: [PATCH v5 0/9] libata cleanups and improvements
Date: Tue, 10 Aug 2021 14:49:30 +0900	[thread overview]
Message-ID: <20210810054939.30760-1-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.

Changes from v4:
* Fixed patch 1 to avoid an out-of-bounds array access
* Changed title of patch 3 to describe the change (as opposed to only
  mentioning the tool that found the problem)
* Removed patch 10 from this series as Martin took it through the scsi
  tree
* Added reviewed-by tags

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
