[Yang, Xiaowei]

In xenstore_parse_domain_config(), 'any_hdN' is overridden by local version 
accidentally.

Thanks for spotting this.  You're right that it's a bug.  I've applied
your patch (although really I think this whole area is pretty grotty
and could do with substantial rework).

Two comments though about the formatting of your patch:

 * It didn't apply cleanly because it had different whitespace to
   that in the actual code.  Your mailer must have done something to
   it I think.  Best practice seems to be (if you can't make your
   mailer reliably not mangle the body of the message) to provide each
   patch _both_ as an attachment (for application) _and_ by including
   it in the body (for readable review).

 * You forgot the Signed-off-By line, by which you would certify that
   the code copyright and so forth status was appropriate (according
   to the Developer's Certificate of Origin).  I applied your patch
   anyway because it's a one-line change (which most authorities think
   makes it too small for copyright to apply) but you should make sure
   to appropriately certify your code in future.

Thanks,
Ian.

There must be something wrong when I did the paste.

Thanks for the advice. I'll attach the patch also next time.

I added the signed-off-by line at the bottom!:)

So you did, sorry!
