Hi Neil I saw your patch "md/raid5: avoid livelock caused by non-aligned writes". That patch is only for RAID 6, but we are seeing similar livelock on RAID5 (mdX_raid5 is constantly looping in raid5d/handle_active_stripes/handle_stripe/ops_run_io and some submitted bios get stuck). The livelock happens when we issue I/O and simulate disk failure. Do you think that the same issue could happen on RAID5 too? Do you think that the patch "md/raid5: fetch_block must fetch all the blocks handle_stripe_dirtying wants." could fix it?
