...ded a new patch, in order to make this work with Christoph Hellwig's recent overhaul to bio_release_pages(): "block: bio_release_pages: use flags arg instead of bool". I've started the series with a patch that I've posted in another series ("mm/gup: add make_dirty arg to put_user_pages_dirty_lock()"[1]), because I'm not sure which of these will go in first, and this allows each to stand alone. Testing: not much beyond build and boot testing has been done yet. And I'm not set up to even exercise all of it (especially the IB parts) at run time. Anyway, changes here a...

...kmalloc memory), so we really should not take a reference either. In other words: the only time we should ever have to put a page in this patch is when they are user pages. We'll need to clean up various bits of code for that, but that can be done gradually before even getting to the actual put_user_pages conversion.
