The updates included in this pull request for ftrace are: ...
o Several clean ups to the code
One such clean up was to convert to 64 bit time keeping, in the
ring buffer benchmark code.
o Adding of __print_array() helper macro for TRACE_EVENT()
o Updating the sample/trace_events/ to add samples of different ways to
make trace events. Lots of features have been added since the sample
code was made, and these features are mostly unknown. Developers
have been making their own hacks to do things that are already available.
o Performance improvements. Most notably, I found a performance bug where
a waiter that is waiting for a full page from the ring buffer will
see that a full page is not available, and go to sleep. The sched
event caused by it going to sleep would cause it to wake up again.
It would see that there was still not a full page, and go back to sleep
again, and that would wake it up again, until finally it would see a
full page. This change has been marked for stable.
Other improvements include removing global locks from fast paths.
