>Description:
	It is not possible to define a dumpdev for kernel crash dumps on a swap
	partition above a gjournal provider. The reason is the missimg handling 
        of "GEOM::kerneldump" in g_journal.c.
	
>How-To-Repeat:
        The command dumpon /dev/mirror/gm0.journalb fails with the message
        dumpon: ioctl(DIOCSKERNELDUMP): Operation not supported.
	
>Fix:
