Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git
tags/fuse-update-6.16
- Remove tmp page copying in writeback path (Joanne). This removes
~300 lines and with that a lot of complexity related to avoiding
reclaim related deadlock. The old mechanism is replaced with a
mapping flag that tells the MM not to block reclaim waiting for
writeback to complete. The MM parts have been reviewed/acked by
respective maintainers.
- Convert more code to handle large folios (Joanne). This still just
adds the code to deal with large folios and does not enable them yet.
- Allow invalidating all cached lookups atomically (Luis Henriques).
This feature is useful for CernVMFS, which currently does this
iteratively.
- Align write prefaulting in fuse with generic one (Dave Hansen)
- Fix race causing invalid data to be cached when setting attributes
on different nodes of a distributed fs (Guang Yuan Wu)
- Update documentation for passthrough (Chen Linxuan)
- Add fdinfo about the device number associated with an opened
/dev/fuse instance (Chen Linxuan)
- Increase readdir buffer size (Miklos). This depends on a patch to
VFS readdir code that was already merged through Christians tree.
- Optimize io-uring request expiration (Joanne)
- Misc cleanups
There's conflict with commit 74e6ee62a894 ("fuse: drop usage of
folio_index") the first hunk of which just gets evicted with the tmp
page cleanup and the second one needs to apply the trivial
folio_index(folio) -> folio->index conversion to my version.
Resolution attached.
Thanks,
Miklos
