I don't believe Dominik is working on quite the same thing, but his
work will conflict with mine for sure:
https://lore.kernel.org/lkml/YxiXEJ6up6XEW8SM@zx2c4.com/T/

What are the odds that two people are making changes to the hwrng
kthread at the same time?

I see two possible ways forward:
1. Dominik rebases his patch against mine (iff mine finds favour).
This may simplify his patch
quite a bit, because the delayed_work abstraction tends to have fewer
footguns than
kthread.

or

2. I rebase against Dominik's.

Both are fine with me, just let me know what you think.
