Convert fs/io_uring to use the new pin_user_pages() call, which sets
FOLL_PIN. Setting FOLL_PIN is now required for code that requires
tracking of pinned pages, and therefore for any code that calls
put_user_page().

In partial anticipation of this work, the io_uring code was already
calling put_user_page() instead of put_page(). Therefore, in order to
convert from the get_user_pages()/put_page() model, to the
pin_user_pages()/put_user_page() model, the only change required
here is to change get_user_pages() to pin_user_pages().

You dropped my reviewed-by now... Given the file, you'd probably want
to keep that.

Hi Jens,

Yes, I was being too conservative I guess. I changed the patch somewhat
and dropped the reviewed-by because of those changes...I'm adding it
back for v7 based on this, thanks!

thanks,
