Happy with the 9p changes:

Having all of these in a single commit makes it difficult to deal but I
don't expect any conflict on my end, so happy to have it go in your
fscache tree.

As far as I'm concerned this is just an "it's always been like this"
thing for me/9p, I wouldn't mind if it were all converted to normal
comments -- but now it's describing arguments by name having it as
kerneldoc has helped catch comments which didn't get updated when
function changed quite a few times in patches similar to this one so it
would only make sense if we remove obvious argument descriptions as well
in my opinion, and that's a bit of manual work.
