From c8f6f88d25929ad2f290b428efcae3b526f3eab0 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Thu, 22 Feb 2024 22:17:23 +0900 Subject: 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.
