From: Ihor Solodrai <ihor.solodrai@pm.me> mainline inclusion from mainline-v6.13-rc6 commit ef7009decc30eb2515a64253791d61b72229c119 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IDC9YK Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... -------------------------------- The selftests are falining to build on current tip of bpf-next and sched_ext [1]. This has broken BPF CI [2] after merge from upstream. Use appropriate function names in the selftests according to the recent changes in the sched_ext API [3].
