[ltt-dev] [PATCH 0/2] Make lttng support enable/disable trace channel

[Zhaolei]

Hello, Mathieu

As we discussed in "Re: [ltt-dev] Make lttctl use new interface",
we need make lttctl select some of channel to trace.

At first step, we need make lttng support link part of channels into a trace.
It is implemented by this patch.

step2: make ltt-trace-control support this function.
step3: make user-more lttctl support this function.

B.R.
