ata_dev_configure() starts off by clearing all flags in ATA_DFLAG_CFG_MASK: dev->flags &= ~ATA_DFLAG_CFG_MASK; ata_dev_configure() then calls ata_dev_config_lba() which calls ata_dev_config_ncq(). ata_dev_config_ncq() will set the correct ATA_DFLAGs depending on what is actually supported. Since these flags are set by ata_dev_configure(), they should be in ATA_DFLAG_CFG_MASK and not in ATA_DFLAG_INIT_MASK. ATA_DFLAG_NCQ_PRIO_ENABLED is set via sysfs, is should therefore not be in ATA_DFLAG_CFG_MASK. It also cannot be in ATA_DFLAG_INIT_MASK, because ata_eh_schedule_probe() calls ata_dev_init(), which will clear all flags in ATA_DFLAG_INIT_MASK. This means that ATA_DFLAG_NCQ_PRIO_ENABLED (the value the user sets via sysfs) would get silently cleared if ata_eh_schedule_probe() is called. While that should only happen in certain circumstances, it still doesn't seem right that it can get silently cleared. (ata_dev_config_ncq_prio() will still clear the ATA_DFLAG_NCQ_PRIO_ENABLED flag if ATA_DFLAG_NCQ_PRIO is suddenly no longer supported after a revalidation.) Because of this, move ATA_DFLAG_NCQ_PRIO_ENABLED to be outside of both ATA_DFLAG_CFG_MASK and ATA_DFLAG_INIT_MASK.
