We separated it into 3 steps,
(in 2008-10-20's ltt-maillist with title of "TODO list before releasing LTTng-buffering to LKML]")
and now we have finished a phototype of step1.
It step1's src is confirmd, we will continue step2 and 3.

We will send you src of step1 today(based on 2.6.27.2-lttng-0.46).
