From: Peter Zijlstra <peterz@infradead.org> stable inclusion from stable-v6.6.66 commit 24617f9ca8c82a9a0b89169a909a26b9751a31e2 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 c708a4dc5ab547edc3d6537233ca9e79ea30ce47 ] Now that trace_sched_stat_runtime() no longer takes a vruntime argument, the task specific bits are identical between update_curr_common() and update_curr().
