[GIT PULL] fuse update for 4.17

[Miklos Szeredi]

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git for-linus

Late pull request, sorry.  I just totally forgot about it, probably because fuse
updates are so rare these days (hoping to get back to regular fuse updates once
overlayfs is "finished").

This contains a few fixes and minor improvements, but the most interesting part
is user namespace support, mostly done by Eric Biederman.  This doesn't yet
enable unprivileged mounting of fuse filesystems, but that's now a really simple
step, since all support for that should be in place.

Thanks,
Miklos
