[GIT PULL] fuse update for 4.18

[GIT PULL] fuse update for 4.18

[Miklos Szeredi]

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git tags/fuse-update-4.18

The most interesting part of this update is user namespace support, mostly
done by Eric Biederman.  This enables safe unprivileged fuse mounts within
a user namespace.

There are also a couple of fixes for bugs found by syzbot and miscellaneous
fixes and cleanups.

Thanks,
Miklos
