Hi Jens,

In case you would prefer to do this, I've updated my iov-extract[*] branch to
put these two patches at the bottom and pushed the other patches back on top
of it, dropping the pipe extraction bits from the iov_iter_extract_pages()
patch in case you want to use that.

I've also removed the FOLL_PIN that was in that patch as it's implied by
calling pin_user_pages_fast() and is being made private to mm/.

I can also repost the full set of patches if that would be useful.

David
