New Revision: 244922
URL: http://svnweb.freebsd.org/changeset/base/244922

Log:
  MFC r244369 (jimharris):
  
  Use CAM_DEV_NOT_THERE instead of CAM_SEL_TIMEOUT to report nonexistent
  LUNs for the virtual processor device.  This removes lots of CAM warnings,
  and follows similar recent changes to tws(4) and twa(4) drivers.
  
  Also fix case where CAM_REQ_CMP was getting OR'd with CAM_DEV_NOT_THERE
  in the nonexistent LUN case, resulting in different CAM status (CAM_UA_TERMIO)
  getting reported to CAM.  This issue existing previously, but was more subtle
  because it changed CAM_SEL_TIMEOUT to CAM_CMD_TIMEOUT.
