In patch 1/9 the BLK_ZONED_* constants have been introduced. The above code compares the bdev_zoned() return value against 0. That means that the above code will break if the numeric value of the BLK_ZONED_* constants would be changed. Please change the above code such that it compares the bdev_zoned() return value against a BLK_ZONED_* constant.
