Hi,
This v4 of series contains a mix of bug fixes and cleanups for RAID10,
along with a related atomic write fix for RAID1.
Changes in v4:
- Improve the commit message of patch 2.
- Add Reviewed-by tag from John Garry to patch 2.
- Link to v3: https://lore.kernel.org/linux-raid/20260708101341.473750-1-abd.masalkhi@gmail.com/
Changes in v3:
- Set chunk_sectors to BARRIER_UNIT_SECTOR_SIZE instead of setting
atomic_write_hw_unit_max.
- Avoid enabling write-behind when the atomic write exceeds the
write-behind limit.
- Link to v2: https://lore.kernel.org/linux-raid/20260628142420.1051027-1-abd.masalkhi@gmail.com/
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@gmail.com/
