Sure, we can do that (for the semi-colon clean up).

No, Mark is right in this case. This IS a separate change, and deserves
a separate patch. This patch is to remove the semi-colons. This change
should be separated out and stated it is for the array. In fact, you
should probably have two different patch sets. One for the semi-colon
clean up, which I'm fine with. And another set that does more to the
patch, like this change. If I do the array change and find that it
doesn't help much, I wont want this change. But I'm willing to keep the
semi-colon change.

Yes, when I convert ftrace and perf to use arrays, then this will be
needed, but it is not needed for this series. I haven't looked at the
other patches yet (besides the first one), but if you have more of this
in other patches, please remove it. You can make another patch set that
I can use before the ftrace/perf updates.
