Which means it real doesn't need its mount anyore, and thus can use
plain old shmem_file_setup and doesn't need to mess with file system
types at all.

Assuming we find a legitimate rason for why a driver should be able
to create a kernel mount or a file system type where it doesn't have
access to the struct file_system_type an API that mount by file system
name and thus hides the get_fs_type and put_filesystem would be a much
better API than adding this random export.
