From: Omar Sandoval <osandov@fb.com> Hi, This is my series to improve the heuristics used by Kyber. Patches 1 and 2 are preparation. Patch 3 is a minor optimization. Patch 4 is the main change, and includes a detailed description of the new heuristics. Patch 5 adds tracepoints for debugging. This is basically the same as the RFC I posted back in August [1] with one added tracepoint (kyber_throttled) and rebased on linux-block/for-next.
