Subject: [PATCH 0/3] ftrace: add sample code with dynamic ftrace_ops

This series adds sample code to manipulate dynamic ftrace_ops, which
I've been using to benchmark/test some changes I've been making in this
area for arm64.

In the process of writing that I spotted a couple of minor issues,
addressed by the first two patches.

I'm not sure whether this should be a sample or something under lib/;
I'm happy to change that if folk have strong opinions.

Thanks;
Mark.
