That looks like a sensible solution and the changelog is good.  A
couple of suggested modifications:

- Don't use the term "pinned" in the changelog without explaining it
  - it's a terribly ambiguous term.  I assume here you mean "pinned by
  elevating the page's refcount"?

- Could we have just one wee little code comment, explaining why
  aio_fs_backing_dev_info exists, what function it is serving?  Put
  yourself in the position of a reader wondering "why is this here".
