runqueue latency bpf fails on newer kernels #286

Closed brayniac closed 2 years ago

brayniac commented 2 years ago

Starting from kernel v5.14 the runqueue latency bpf sampling fails due to the state field of the task_struct being renamed.

To Reproduce Steps to reproduce the behavior:

  1. On a system with kernel >= 5.14 with Rezolus installed
  2. Configure Rezolus to enable scheduler bpf sampling
  3. Run Rezolus
  4. See error

Resolved with #287 and #288
