+Subject: [PATCH 018/323] sched: Add migrate_disable() tracepoints
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+XXX write a tracer:
+
+ - 'migirate_disable() -> migrate_enable()' time in task_sched_runtime()
+ - 'migrate_pull -> sched-in' time in task_sched_runtime()
+
+The first will give worst case for the second, which is the actual
+interference experienced by the task to due migration constraints of
+migrate_disable().
