This is still missing kerneldoc comments for the newly exported
functions.

And for this one I haven't even heard back on my review comments.  None
of them is a merge blocker so it's not critical, but I find it quite odd
that the pull request is coming before even replying to the review
comments.

Can you resend your e-mail, please?  I can't seem to find it in my
inbox.  Thanks!!

It was just a paragraph in the mail also commenting on the previously
core parts:

I've got a comment from Jan that the no buffers case can still happen,
so that can be removed.

Any chance you could also look into the kerneldoc comments for the newly
exported fs/mpage.c routines as commented on the updated patch?
