This patchset adds support for folios larger than one page size in FUSE. This patchset is rebased on top of the (unmerged) patchset that removes temp folios in writeback [1]. (There is also a version of this patchset that is independent from that change, but that version has two additional patches needed to account for temp folios and temp folio copying, which may require some debate to get the API right for as these two patches add generic (non-FUSE) helpers. For simplicity's sake for now, I sent out this patchset version rebased on top of the patchset that removes temp pages) This patchset was tested by running it through fstests on passthrough_hp.
