Knowing that the upstream project provides a "ready to use" version of the kernel, it's good to include an easy way to users to monitor performance, and that's what we're doing by enabling the TASKSTATS (and related) kernel configs. This has been present as part of older kernels, but I couldn't reasonably find the reason why it's been dropped.
