Out of curiosity, do you maintain a branch of LTTNG versus any of the
-rc kernels, or do you only track the stable kernels?  I tried pulling
LTTNG 0.78 against the most recent Linus mainline and got a whole pile
of conflicts.

I then tried building LTTng 0.78 and got build failures:

  CC      arch/x86/kernel/init_task.o

Looks like CONFIG_MARKERS_USERSPAC is busted....
