Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git
tags/fuse-update-6.9
- Add passthrough mode for regular file I/O. This allows performing
read and write (also via memory maps) on a backing file without
incurring the overhead of roundtrips to userspace. For now this is
only allowed to privileged servers, but this limitation will go away
in the future. (Amir Goldstein)
- Fix interaction of direct I/O mode with memory maps (Bernd Schubert)
- Export filesystem tags through sysfs for virtiofs (Stefan Hajnoczi)
- Allow resending queued requests for server crash recovery (Zhao Chen)
- Misc fixes and cleanups
There's a conflict in fs/fuse/inode.c. The resolution (attached) is
to leave the fuse_backing_files_free() call in fuse_conn_put(), before
call_rcu().
Thanks,
Miklos
