Hello Gioh,

Thank you for your answer.

If this tracer is justifiable, I think that making it conditional is
better than just enabling always on CONFIG_CMA_DEBUGFS. Some users
don't want to this feature although they enable CONFIG_CMA_DEBUGFS.



Thanks for your work. It must be helpful to me.

What about add another option to activate stack-trace?
In my platform I know all devices using cma area, so I usually don't
need stack-trace.

So Joonsoo suggests to add an option for buffer list, and you suggest to
add another in addition to the first one (and also add CONFIG_STACKTRACE
to dependences) right?

Right. Another option for only stack-trace might be good.
