Hi Martin, In ZBC-2 support has been improved for zones with a size that is not a power of two by allowing host-managed devices to report gap zones. This patch adds support for zoned devices for which data zones and gap zones alternate if the distance between zone start LBAs is a power of two. Please consider this patch series for kernel v5.19. Thanks, Bart. Changes compared to v1: - Made this patch series compatible with the zone querying code in BTRFS. - Addressed Damien's off-list review comments. - Added patch "Return early in sd_zbc_check_zoned_characteristics()" to this series.
