did you look at kern_mount/umount interface that went into the kernel
recently? Things like shm and pipefs should (and already are) mounted
under artificially constructed root mountpoints like "pipe:" which are not
visible for namelookups coming from userspace. Ok, it is not the case for
shm currently (it is mounted on /) but perhaps it should be (i.e. the way
root dentry should be allocated as for pipefs using d_alloc() directly
instead of using generic d_alloc_root())?
I cc'd Al Viro as I suspect he knows the answer to the above question.
