  SVN rev 212229 on 2010-09-05 14:27:55Z by kib
  
  MFC r210923:
  Add new make_dev_p(9) flag MAKEDEV_ETERNAL to inform devfs that created
  cdev will never be destroyed. Propagate the flag to devfs vnodes as
  VV_ETERNVALDEV. Use the flags to avoid acquiring devmtx and taking a
  thread reference on such nodes.
