No this patch wastes a lot of developers time. If we accept it, than any patch that is added after it will need to be rebased before going to Linus. Unless KVM is made up of a bunch of branches like tip is, this will become more of a hassle than a benefit. Ingo's tip/master is based off of a bunch of branches. It is not recommended to develope against tip/master. I develop against tip/tracing/core, because that is what will get pulled by Linus. tip/master is created automatically from a bunch of branches and gets rebased all the time. One of those branches is tip, which supplies the localversion. Thus, if you use tip/master, you get the localversion file. But if you develop against one of the main branches that will eventually go to Linus, then you will not have that localversion file. -- Steve -- 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
