Ah I see what you're saying.

Well in my case, I just want driver work to not charge the process cpu time.

But I get what you're saying, Checking if new configurations are valid
shouldnt block on existing configurations getting applied.

Doing it outside the locks isn't necessary to prevents deadlocks, it's
necessary because you're trying to avoid contention when there doesn't
need to be contention.

Your patchset sort of has a different goal, but it solves the issue I
care about at the same time.

I'd be happy if it went in... Daniel, Dave, what are your takes on this?
