From: Zhang Yi <yi.zhang@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.

Hi, Jens! Can you take this patch set through the linux-block tree? Thanks, Yi.
