Ah... I didn't realize this was talking about a suid-root wrapper for mount. I misunderstood the 'users who are allowed to perform unprivileged mounts' and thought it was talking about some kernel setting to allow non-root users to call mount(2).

So what this change really does is make it more straightforward to implement a secure suid-root wrapper for mount(2) in user space.

I thought that's what it was as well. I know Miklos eventually wants to be able to have random users call mount() and umount() for their own FUSE filesystems on mount points they own without relying on a setuid wrapper.
