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.


Miklos Szeredi (9):
fuse: fix use after free in fuse_read_interrupt()
fuse: name fs_context consistently
fuse: move option checking into fuse_fill_super()
fuse: move fget() to fuse_get_tree()
fuse: allow sharing existing sb
fuse: truncate pagecache on atomic_o_trunc
fuse: flush extending writes
fuse: wait for writepages in syncfs
fuse: remove unused arg in fuse_write_file_get()
