[Sean Bruno]

Author: sbruno

New Revision: 249652
URL: http://svnweb.freebsd.org/changeset/base/249652

Log:
  MFC r249170
  
  Notify CAM on state* change to a logical volume not status.  This resolves
  the issues reported regarding camcontrol devlist not showing the rebuild
  states of volumes unless an explicit camcontrol rescan was executed.
