Have you tried Linus's tree to see if this works yet? If not, it should
be a simple fix. See 7cfc630e63b4 ("proc "single files": switch to
->read_iter") as an example of what is needed here.
I think we will see a lot of these "/proc files need to be fixed up"
issues over time as this is something that we hit in the 5.10-rc
sequence and fixed a bunch of them already...
