Martin, Two patches for this cycle (with a cc stable) to fix handling of host-aware ZBC disks that have partitions, that is, used as regular disks. The first patch fixes host-aware disk initialization and command completion processing. It also enables the use of host-aware disks as regular disks when CONFIG_BLK_DEV_ZONED is disabled. The second patch fixes the CONFIG_BLK_DEV_ZONED enabled configuration so that zone append emulation is not initialized for host-aware disks with partitions/used as regular disks. While at it, this patch also removes a problem with sd_zbc_init_disk() error handling in sd_revalidate_disk() by moving this function execution inside sd_zbc_revalidate_zones(). Borislav tested the previous version of this series and confirmed that it solves his problem (thanks Borislav !) Changes from v2: * Introduce blk_queue_set_zoned() helper function Changes from v1: * Rebased on rc5 * Use "if (IS_DEFINED())" instead of #ifdef in patch 1 Damien Le Moal (2): scsi: Fix handling of host-aware ZBC disks scsi: Fix ZBC disk initialization block/blk-settings.c | 46 +++++++++++++++++++++++++++++ drivers/scsi/sd.c | 34 ++++++++++++---------- drivers/scsi/sd.h | 8 +---- drivers/scsi/sd_zbc.c | 66 +++++++++++++++++++++++++----------------- include/linux/blkdev.h | 2 ++ 5 files changed, 107 insertions(+), 49 deletions(-) -- 2.26.2
