[PATCH v2 0/7] md/raid10: fixes, atomic write handling, and error-path cleanup

[Abd-Alrhman Masalkhi]

Hi,

This v2 of series contains a mix of bug fixes and cleanups for RAID10,
along with a related atomic write fix for RAID1.

Changes in v2:
 - Expand the commit message to explain why the
   allow_barrier()/wait_barrier() pair is no longer needed.
 - Drop the early atomic write split check from raid1_write_request().
 - Advertise the atomic write size limit via queue limits.
 - Disable write-behind instead of failing atomic writes when the
   BIO_MAX_VECS limit is encountered.
 - Drop the early atomic write split check from raid10_write_request()
   and rely on queue limits instead.
 - Fix a compilation error (bi -> bio).
 - Link to v1: https://lore.kernel.org/linux-raid/20260623072456.333437-1-abd.masalkhi@xxxxxxxxx/

Thanks,
Abd-alrhman,
