[GIT PULL] fuse update for 5.15

[Miklos Szeredi]

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git tags/fuse-update-5.15

- Allow mounting an active fuse device.  Previously the fuse device would
  always be mounted during initialization, and sharing a fuse superblock
  was only possible through mount or namespace cloning

- Fix data flushing in syncfs (virtiofs only)

- Fix data flushing in copy_file_range()

- Fix a possible deadlock in atomic O_TRUNC

- Misc fixes and cleanups

The recent commit dates for the two head commits are due to a trival bug
fix being folded in.

Thanks,
Miklos
