back in the scheduler, and then start trying again, I do not see how you
can guarantee that retrying the unaligned writes will ever succeed.
I am talking in the context of host-managed devices here.
Hi Damien,
How about changing the NEEDS_RETRY in patch 7/8 into another value than
SUCCESS, NEEDS_RETRY or ADD_TO_MLQUEUE? That will make the SCSI core
wait until all pending commands have finished before it starts its error
handling strategy and before it requeues any pending commands.
Thanks,
Bart.
