New Revision: 259173
URL: http://svnweb.freebsd.org/changeset/base/259173

Log:
  Merge r258758 (by adrian) from head:
  
    Make sure any waiters on the scan results get notified if the scan task
    decides to do nothing.
  
    If this isn't done, then a scan request whilst a scan occurs in an
    active channel set or a completed channel set will hang.
  
  Candidate for 10.0.
