Additional remark: you should split the retry mechanism and callback
addition to separate commits as they must be reasoned separately. See
the section one in:

https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html

"If your changes produce a lot of deltas, you need to split them into
individual patches which modify things in logical stages; see 3)
Separate your changes. This will facilitate review by other kernel
developers, very important if you want your patch accepted."
