Shin'ichiro Kawasaki 2d669ceb69 dm table: Fix zoned model check and zone sectors check ... Commit 24f6b6036c ("dm table: fix zoned iterate_devices based device capability checks") triggered dm table load failure when dm-zoned device is set up for zoned block devices and a regular device for cache. The commit inverted logic of two callback functions for iterate_devices: device_is_zoned_model() and device_matches_zone_sectors(). The logic of device_is_zoned_model() was inverted then all destination devices of all targets in dm table are required to have the expected zoned model. This is fine for dm-linear, dm-flakey and dm-crypt on zoned block devices since each target has only one destination device. However, this results in failure for dm-zoned with regular cache device since that target has both regular block device and zoned block devices. As for device_matches_zone_sectors(), the commit inverted the logic to require all zoned block devices in each target have the specified zone_sectors. This check also fails for regular block device which does not have zones. To avoid the check failures, fix the zone model check and the zone sectors check. For zone model check, introduce the new feature flag DM_TARGET_MIXED_ZONED_MODEL, and set it to dm-zoned target. When the target has this flag, allow it to have destination devices with any zoned model. For zone sectors check, skip the check if the destination device is not a zoned block device. Also add comments and improve an error message to clarify expectations to the two checks.
