Jens, The first patch of this series extracts and extends a fix included in the zone append series to correctly handle writes to null_blk zoned devices. The fix forces zone type and zone condition checks to be executed before the generic null_blk bad block and memory backing options handling. The fix also makes sure that a zone write pointer position is updated only if these two generic operations are executed successfully. The second patch is from Johannes series for REQ_OP_ZONE_APPEND support to clean up null_blk zoned device initialization. The reviewed tag from Christoph sent for the patch within Johannes post is included here. Please consider these patches for inclusion in 5.7.
