Let me ask a more general question, before considering whether to ack: When kconfig was introduced into Xen, the expectation was (iirc) that we wouldn't grow its use to the fine grained granularity that it has been having in Linux. The more build-time controls we have, the harder it is to know whether a certain piece of code was actually included in a build someone, say, reports a problem with. Are we knowingly moving away from that earlier position? evtchn_fifo.c isn't actually that much code to exclude, after all ... Jan
