From 9865f31d852a40e39b8efb8feec69182e1002489 Mon Sep 17 00:00:00 2001 From: Changwoo Min Date: Tue, 4 Feb 2025 14:20:55 +0900 Subject: [PATCH] sched_ext: Add scx_bpf_events() and scx_read_event() for BPF schedulers 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.
