| |
dm_zone_endio() updates the bi_sector of orig bio for zoned devices that uses either native append or append emulation and it is called before the endio of the target. But target endio can still update the clone bio after dm_zone_endio is called, thereby, the orig bio does not contain the updated information anymore. Call dm_zone_endio for zoned devices after calling the target's endio function
