Hi,

The namespace statedump and contexts feature has not been merged in
master yet. You can get it from my github in the "ns" feature branches.

https://github.com/mjeanson/lttng-modules/tree/ns
https://github.com/mjeanson/lttng-ust/tree/ns
https://github.com/mjeanson/lttng-tools/tree/ns

It's a bit out of date but should work as-is, or it can be easily
rebased on current master branches.


Cheers,

Michael
