Greg,
There were a lot of changes to fix a few bugs in ftrace. There is a race
where you can crash the kernel (needing root privileges) and it
required a bit of a redesign to fix it. These changes have been in
linux-next for a while, and then it has been in mainline for a while
after that. I think they were all added around 3.11-rc4.
Anyway, I'm finally happy enough with them to push them to 3.10
stable.
I threw in Namhyung Kim's clean up. It's not really that urgent of
a fix, but as it was thrown into the rest of my changes, it's been
tested just as much.
Note, these are all based off of 3.10.9, and tested off of that
too.
