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 Damien Le Moal (10): libata: fix ata_host_alloc_pinfo() libata: fix ata_host_start() libata: fix sparse warning 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 libahci: Introduce ncq_prio_supported sysfs sttribute scsi: mpt3sas: Introduce sas_ncq_prio_supported sysfs sttribute drivers/ata/libahci.c | 1 + drivers/ata/libata-core.c | 288 ++++++++++++++++------------- drivers/ata/libata-sata.c | 61 +++--- drivers/ata/libata-scsi.c | 60 +----- drivers/scsi/mpt3sas/mpt3sas_ctl.c | 19 ++ include/linux/libata.h | 5 + 6 files changed, 227 insertions(+), 207 deletions(-) -- 2.31.1
