Committed By:   bouyer
Date:           Sun Aug  7 17:39:34 UTC 2011

Modified Files:
        src/sys/arch/xen/xen: xbdback_xenbus.c

Log Message:
Guard against spurious xbdback_backend_changed() calls which would result
in the block device being opened twice. Fixes port-xen/45158,
although the underlying cause (multiple open of the same device not
properly handled any more) is not fixed.
