Subject: [GIT PULL] fuse update for 6.15

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git
tags/fuse-update-6.15

- Allow connection to server to time out (Joanne Koong)

- If server doesn't support creating a hard link, return EPERM rather
than ENOSYS (Matt Johnston)

- Allow file names longer than 1024 chars (Bernd Schubert)

- Fix a possible race if request on io_uring queue is interrupted
(Bernd Schubert)

- Misc fixes and cleanups

Commit 1dfe2a220e9c ("fuse: fix uring race condition for null
dereference of fc") in this queue has already been merged into
v6.14-final through Christian's tree (commit d9ecc77193ca).   For some
reason this causes a merge conflict, the resolution of which is to
just take the version from this pull (i.e. remove the atomic_set()).

Thanks,
Miklos
