No, userspace mounts the fs to /selinux.

If the kernel patch is merged (and it will, given that Dan okey'd it)
this wil just create an empty directory in /sys/fs/selinux suitable as
mount point. That's all. Whether this is actually used as mount point is
left to userspace.

Merging the kernel patch is pretty much risk-less. The transition to it
can happen at a later point, slowly, at a pace defined by Dan.
