The new spinlock that the problem is in was introduced in kernel 5.15, which is relatively new, you need to be hooking context switches, and you need to be sampling at a high enough frequency that you hit the problem, and you need to be using the ring buffer to emit those events. Outside of CPU profilers like us, I don't think there are many other eBPF applications with this type of setup.
