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@xxxxxxxxx/ 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@xxxxxxxxxxxxxx/ 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.
