block: Clear zone limits for a non-zoned stacked queue
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. Fixes: 3093a479727b ("block: inherit the zoned characteristics in blk_stack_limits") Cc: stable@vger.kernel.org Signed-off-by: Damien Le Moal <dlemoal@kernel.org> Link: https://lore.kernel.org/r/20240222131724.1803520-1-dlemoal@kernel.org Signed-off-by: Jens Axboe <axboe@kernel.dk>
