Hi,I'm a graduate student from China. Due to my last experience using SystemTap
to trace kernel's submit_bio() function activity in my recent research on disk
blocks' correlation, I get interested in system trace tool .So I think
contributing to lttng in GSoC would be a great adventure.
According to the idea page, the kernel side tracer has no comparable filtering
mechanism like the one in user-space side however, it is proposed that the
filtering be implemented in the babeltrace , rather than in kernel side. Can
you please tell me the reason?
Nevertheless, I think implementing a usable and relatively optimized filter is
a great work worth working on. I have read the man page and tested the
toolchain. Now I have got a whole picture of it. And in order to get familiar
with you guys and prove my skills I should try to submit patches to this list,
right? Beside that I hope hear your discussion on filter mechanism.
Best regards,
Lingyu Zhu
