Subject: [RFC PATCH v6 0/2] Make eBPF programs output data to perf

Hi,

Previous patch v5 url:
http://thread.gmane.org/gmane.linux.kernel/1995274

The bugfix of dynamic array length in trace event goes to
kernel/git/rostedt/linux-trace.git ftrace/urgent and confirms that the
return value of __get_dynamic_array_len() is the total allocated
length of the dynamic array. For we print the bpf output data in byte
array from patch v5, that problem does not affect our patch any more,
but some comments in patch 1/2 is updated.

Patch 2/2 is acked by Alexei.

Thank you.
