Why do you replace use of the schedop_block hypercall with direct setting of the blocked flag and softirq? Also vcpu_kick() has negligible extra cost compared with vcpu_unblock() and it's less confusing just to use it everywhere. Most people don't remember the semantic difference. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
