Ah sorry, got distracted by other work.
OK, I just tried it out, and here's my results:
I ran you code with my current kernel and this is what I got:
# ./ftrace-test-epoll-kafai
<...>-3183 [002] ...1 81.777891: tracing_mark_write:
some data 3183: waitting for more data......
3184: written more data
And it just hung there.
Then I applied your patch, compiled and booted it, and ran the test
again, and I got this:
# ./ftrace-test-epoll-kafai
It just hung there. No forward progress.
I don't think that was the result you intended.
