So the code in domain_crash_synchronous() is just a warning for errant code -- later it can become BUG_ON(). This means that multicall state can remain per-cpu, unless per-vcpu seems much better (personally I think it doesn't really matter either way so we may as well stick with what we have). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
