Using poll(2) on trace files

[Aryeh Weinreb]

Hi,

I would like to process the systemtap trace files in userspace without
writing to disk.
I built the kernel module with stap -p4 then loaded it with staprun -L.
I would like to use poll(2) on the trace0 file to wait for data but I am
not getting POLLIN set even though there is data I can read from the file.
What am I missing?

Thanks,
Aryeh
