Subject: mini-os: drop shutdown variables when CONFIG_XENBUS=n
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d3fc78cd3a78f8d241c35f254fd389412c7cb9c2;p=people%2Fliuw%2Flibxenctrl-split%2Fmini-os.git

mini-os: drop shutdown variables when CONFIG_XENBUS=n

Shutdown variables are meaningless when CONFIG_XENBUS=n since no
shutdown event will ever happen.  Better make sure that no code tries
to use it and never get the hoped shutdown event.
