Hello.
On top of "PATCH 0/3] tracing: more list_empty(perf_events) checks"
series I sent yesterday.
Compile tested only, not for inclusion yet.
But I'll appreciate if you can take a look. I'll try to test this
tomorrow somehow and let you know. Right now I am looking at asm code,
looks correct...
I also compiled the kernel with the additional patch below, everything
compiles except sched/core.o as expected.
Oleg.
