It's already supposed to be serialised, and there's a loop in xen_suspend() to deal with up to one queued suspend request. Your patch may deal with an arbitrary number of queued suspend requests, but a sane dom0 control stack should never issue more than one suspend request in a suspend-resume cycle. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
