Ok, I hope it's not too late.
Here is one subject that I would like to apply for:


= Improving tracing in perf events / ftrace =


Using trace events under perf events is still a young feature
and needs various improvements.

- Syscall events can carry only raw values and addresses.
We need to make them "aware" of strings and structures contents
from userspace.

- Make function / function graph tracers usable by perf

- Optimize tracing fast-path

- Improve perf tools to better handle trace events scalability

- Provide new perf tools that exploit trace events (scheduler
  migration analysis, etc...)

- Implement a per context excluding (eg: exclude irqs, exclude functions, etc...)

- There are always things to do there.


Of course, each of these elements require a lot of work,
so not all of them can be done in two months, and some
of them can be started already before the summer.
