From: Changwoo Min <changwoo@igalia.com> mainline inclusion from mainline-v6.18-rc7 commit 9865f31d852a40e39b8efb8feec69182e1002489 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ID7HLY Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... --------------------------------------- scx_bpf_events() is added to the header files so the BPF scheduler can use it. Also, scx_read_event() is added to read an event type in a compatible way.
