I would like raid request retries to be done with exponential
delays, so that we get a chance to overcome network brownouts.

Hmm, I don't think MD even does retries of requests.

I had a "robust read" patch in FR1, and I thought Neil extended that to
"robust write".  In robust read, we try to make up for a failed read
with info from elsewhere, and then we rewrite the inferred data onto the
failed device, in an attempt to fix a possible defect.  In robust write,
a failed write is retried.  But robust read is enough to cause a retry
(as a write).

It does write-back as a (very successful! Thanks Neil :-D) attempt to
fix bad blocks, but that's a different thing.

Apparently not different :).

Is that what you meant?

Plozzziby.

Or is there something sandwiched between MD and ENBD that performs retries...

Could be too. Dunno.
