If anyone has any objections, please let me know. ------------------ From: Damien Le Moal [ Upstream commit c8f6f88d25929ad2f290b428efcae3b526f3eab0 ] Device mapper may create a non-zoned mapped device out of a zoned device (e.g., the dm-zoned target). In such case, some queue limit such as the max_zone_append_sectors and zone_write_granularity endup being non zero values for a block device that is not zoned. Avoid this by clearing these limits in blk_stack_limits() when the stacked zoned limit is false.
