I usually let the patches stay in next for a few days before
I send pull request. It is getting close to that, so decided
on rc2 as a better choice.

We are at rc-6 at the moment, maybe there is enough time for
this to get into rc-1

This patch has been in the works for a while now. Might as well
get it in.

Bummer. Now this patch conflicts with the following commits:

ftracetest: Convert exit -1 to exit $FAIL
ftracetest: Add basic event tracing test cases

Applying: ftracetest: Do not use usleep directly
error: patch failed:
tools/testing/selftests/ftrace/test.d/event/event-enable.tc:12
error: tools/testing/selftests/ftrace/test.d/event/event-enable.tc:
patch does not apply
error: patch failed:

tools/testing/selftests/ftrace/test.d/event/toplevel-enable.tc:12
error: tools/testing/selftests/ftrace/test.d/event/toplevel-enable.tc:

I could attempt to fix the conflicts, however prefer if you can
rebase it on linux-kselftest next.

thanks,
