Note that using A/D bits introduces new tradeoffs (when just a few bits are dirtied per iteration, we reduce guest overhead, but increase host overhead, since it has to scan a large number of sptes), and also a large fraction of deployed systems don't have A/D bits support. But it should affect our thinking - since in the long term all hosts will have it. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
