Is this easy to reproduce? I haven't seen it locally but then again I have only been running trinity with -c perf_event_open I only left the debug message in because I thought it would be unusual for a quick sysfs traversal to fail. > init_pmus might be simpler if it was converted to use nftw() too. I was unaware of the existence of nftw(), I'll work on updating the code to use it.
