Hi All,

Thanks for joining the call today after a short holiday hiatus. Below are my
notes from the call.

kubernetes environment

- Please give it a spin and contribute/comment on
github.com/iovisor/kubectl-trace
* Nice work Lorenzo!

Yonghong
* funcinfo and line info merged BTF support merged into kernel
