From: Peter Zijlstra <peterz@infradead.org> stable inclusion from stable-v6.6.66 commit 7f509457773e2d358f451c3057e065e7289f3eb7 category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8903 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- [ Upstream commit 5fe6ec8f6ab549b6422e41551abb51802bd48bc7 ] 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.
