You need to do this first for newer kernel trees, and only if they are
accepted there, should you do this for older ones as you do not want to
have regressions moving to newer kernels, right?
But first, why do this at all? You should always be using the latest
kernel version of perf on older kernels, especially if you are updating
glibc.
And if you update glibc, WHY ARE YOU NOT UPDATING YOUR KERNEL?
Why would you be using an old kernel tree like this? That's very odd,
please do not do that.
thanks,
