    sys/kern             subr_mbuf.c 
    sys/sys              mbuf.h 
  Log:
  Add the M_FREELIST flag, which is used to detect whenever a
  double free of a mbuf occurs and cause an immediate panic, rather
  than allowing free list corruption to occur.
  
  This code is trapped under INVARIANTS, so it should not cause any
  change in default performance.
