The new syscall being contemplated by this patch are those already available in the linux-next tree: open_tree(), move_mount(), fsopen(), fsmount(), fspick() and fsinfo(). These system calls were tested with David Howells test case[1], as some others I wrote[2]. For testing purpose, I also made usage of the new, but yet not integrated, fsconfig() syscall.
