  Modified files:
    sys/geom/mirror      g_mirror.c 
  Log:
  This should not be permitted, but some GEOM classes held the topology lock
  while doing g_(read|write)_data() (e.g. BSD). This can cause a deadlock
  in MIRROR class. Not sure if this is safe to drop the topology lock in BSD
  class, so change the code in MIRROR class to avoid this deadlock.
