But it works by patching the kernel, not just using eBPF like many performance tools recently. So it needs active maintenance all the time considering the current velocity of internal kernel changes. And I would not be surprised if it didn't build or work correctly if you have a heavily patched and customized kernel.
On the positive side at a first glimpse the maintenance to adapt to new kernels looks very active.
