From 5fe6ec8f6ab549b6422e41551abb51802bd48bc7 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 6 Nov 2023 13:41:43 +0100 Subject: sched: Remove vruntime from trace_sched_stat_runtime() Tracing the runtime delta makes sense, observer can sum over time. Tracing the absolute vruntime makes less sense, inconsistent: absolute-vs-delta, but also vruntime delta can be computed from runtime delta. Removing the vruntime thing also makes the two tracepoint sites identical, allowing to unify the code in a later patch.
