Why can't the retries be passed down via a new blk req->retries?


Is that all that is needed for dm-multipath? I thought this would be a good time to add some code to allow the finer grained control of retries that could also be used by dm and md. For example do you only want to retry certain failures X numbeer of times?


I was looking/thinking about the scsi_scan retries not multipath.

And I was hoping the same code/framework can be used for scsi, DM, MD, SG_IO and all other block layer drivers.
