See the attached patch.  This patch adds both an authorization (pre) hook
and a post hook to pivot_root, passing the appropriate nameidata
structures at each point.  A security module can implement a permission
check based on these structures after looking up the put_old and new_root
paths, and a security module can update its internal state after a
successfully completed pivot.
