Hi,

This series fixes several write-path failure handling issues in raid1 and
raid10 and then follows up with a cleanup of raid1_write_request().

The first two patches fix writes_pending leaks caused by failure paths
that complete bios without reaching the normal write completion path.
The raid1 fix also addresses a barrier reference leak when
wait_blocked_rdev() fails after wait_barrier() succeeds.

The third patch fixes additional writes_pending and barrier reference
leaks in raid10 discard handling.

The final patch simplifies raid1_write_request() error handling.

Patches:
md/raid1: fix writes_pending and barrier reference leaks on write failures
md/raid10: fix writes_pending leak on write request failures
md/raid10: fix writes_pending and barrier reference leaks on discard failures
md/raid1: simplify raid1_write_request() error handling

Changes in v2:
 - fix writes_pending leaks in addition to the barrier reference leaks
 - add raid10 fixes for analogous write and discard failure paths
 - add a follow-up cleanup patch to simplify raid1_write_request()
 - simplifies raid1_write_request() error handling.
 - Link v1: https://lore.kernel.org/linux-raid/20260611132500.763528-1-abd.masalkhi@gmail.com/

Thanks,
