History
Robert Watson ed6397209d o introduce u_cansee(), which performs access control checks between 
two subject ucreds.  Unlike p_cansee(), u_cansee() doesn't have
  process lock requirements, only valid ucred reference requirements,
  so is prefered as process locking improves.  For now, back p_cansee()
  into u_cansee(), but eventually p_cansee() will go away.
