I don't feel qualified to review these, but some notes. Patch 1. s/avodi/avoid/ in the commit message Patches 2 and 3. You probably want to convert the printks to gdprintk()s, otherwise guests can choke up the ratelimited log. Doing so will also mean that the vcpu will be identified consistently, which it isn't currently. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-devel
