That was my fear, it was so painful that attempt at future changes, scares folks off. :-( So I just spent some time trying to explore your changes a little bit. I thought the VERSION and RELEASE stuff was for the kernel but in fact it really is only for the tools (perf and kernel-tools). Looking at current kernel-tools-debuginfo doesn't show any VERSION and RELEASE stuff. Your patch seems to add that. I guess I am curious why? If you can only have one version of the tools installed at one time, what does VERSION and RELEASE provide us? My thinking is why don't all the other userspace applications need similar naming? Sorry for being picky, just trying to understand those particular changes. The rest of the patch looks fine to me.
