New Revision: 255542
URL: http://svnweb.freebsd.org/changeset/base/255542

Log:
  MFC r252382 (by scottl), r252684 (by jkim):
  Introduce accessors for the ccb status word.  Convert one (of many more)
  modules to use it, will convert the others once the appropriate shed
  color is selected by consensus.
