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 v5: * Updated patch 9 to include adding the new ncq_prio_supported sysfs attribute for SATA adapters other than AHCI. Changed the patch title and commit message accordingly. 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 Damien Le Moal (9): libata: fix ata_host_alloc_pinfo() libata: fix ata_host_start() libata: simplify ata_scsi_rbuf_fill() libata: cleanup device sleep capability detection libata: cleanup ata_dev_configure() libata: cleanup NCQ priority handling libata: fix ata_read_log_page() warning libata: print feature list on device scan libata: Introduce ncq_prio_supported sysfs sttribute drivers/ata/libahci.c | 1 + drivers/ata/libata-core.c | 290 +++++++++++++++++++++----------------- drivers/ata/libata-sata.c | 62 ++++---- drivers/ata/libata-scsi.c | 60 ++------ include/linux/libata.h | 5 + 5 files changed, 212 insertions(+), 206 deletions(-) -- 2.31.1
