I was working on getting timechart running and noticed that it wouldn't
get any sched_switch/wakeup etc events if debugfs is mounted anywhere
other than /sys/kernel/debug/. Mine was mounted in /debug (the second
sane location ;) )

So we'd need something like whats in the patch to make use of the global
debugfs_path.

Also, I'm assuming that parse-events.c is governed by GPLv2 or something
similar ?
