Btw., building perf in parallel to an ongoing kernel compile is something I do almost daily, and I never saw problems due to that. A perf build is not supposed to cause any side effect on the kernel build and vice versa. So in general it should just work. > "Yo Dawg, I heard you like kernel compiles, so I put a kernel compile > in your kernel compile so that you can compile the kernel while you > compile the kernel". Heh, accidental dual kernel builds within the same kernel tree is something I have a _lot_ of involuntary experience with, and I usually recognize the error message patterns straight away ;-) As a kernel hacker one learns useful skills all the time!
