[PATCH 00/11] fuse: convert to using folios and iomap

[Josef Bacik <josef@toxicpanda.com>]

Hello,

This is a prep series for my work to enable large folios on fuse.  It has two
dependencies, one is Joanne's writeback clean patches

https://lore.kernel.org/linux-fsdevel/20240826211908.75190-1-joannelkoong@gmail.com/

and an iomap patch to allow us to pass the file through the buffered write path

https://lore.kernel.org/linux-fsdevel/7f55c7c32275004ba00cddf862d970e6e633f750.1724755651.git.josef@toxicpanda.com/

I've run these through an fstests run with passthrough_hp --direct-io,
everything looks good.

The last remaining bit that needs to be made to use folios is the splice/pipe
code, which I need to be a lot more careful about.  The next step is to plumb
through the ability to handle large folios.  But this is a decent start and
removes the bulk of FUSE's use of struct page, and is relatively safe and
straightforward.  Thanks,

Josef
