[PATCH v2 0/2] Fix the initialization of max_hw_wzeroes_unmap_sectors for stacking drivers

[Zhang Yi]

From: Zhang Yi <yi.zhang at huawei.com>

Changes since v1:
 - Improve commit messages in patch 1 by adding a simple reproduction
   case as Paul suggested and explaining the implementation differences
   between RAID 0 and RAID 1/10/5, no code changes.

v1: https://lore.kernel.org/linux-block/20250825083320.797165-1-yi.zhang@huaweicloud.com/

This series fixes the initialization of max_hw_wzeroes_unmap_sectors in
queue_limits for all md raid and drbd drivers, preventing
blk_validate_limits() failures on underlying devices that support the
unmap write zeroes command.

Best regards,
Yi.
