Merge tag 'md-7.1-20260428' of https://git.kernel.org/pub/scm/linux/kernel/git/mdraid...

Pull MD fixes from Yu Kuai:

"Bug Fixes:
 - Fix a raid5 UAF on IO across the reshape position.
 - Avoid failing RAID1/RAID10 devices for invalid IO errors.
 - Fix RAID10 divide-by-zero when far_copies is zero.
 - Restore bitmap grow through sysfs.

 Cleanups:
 - Use mddev_is_dm() instead of open-coding gendisk checks.
 - Use ATTRIBUTE_GROUPS() for md default sysfs attributes.
 - Replace open-coded wait loops with wait_event helpers."
