Subject: [PATCH v3 0/2] Fix handling of host-aware ZBC disks
Date: Tue, 15 Sep 2020 16:33:45 +0900 [thread overview]
Message-ID: <20200915073347.832424-1-damien.lemoal@wdc.com> (raw)
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
