Just in case somebody tries this series out against kernel v6.7-rc5 ... A problematic perf patch made it into v6.7-rc5 (v6.7-rc4 and before are fine). When testing this series against kernel v6.7-rc5 the splat reported at [1] is triggered. A perf fix [2] is already queued up so all will be fine when testing this series against a kernel with [2] merged.
