The original source doesn't need a LICENSE in the perf package as its part of a bigger repository. This just copies this license to the root of the forked repo.
Use the fix I submitted to acln0/perf instead of the one suggested on the review.
This prevents a common cause of crashes due to live ring-buffer memory being returned by readRawRecordNonblock, which could be overwritten at any time. Also adds some error checks to the ring-buffer reading.
- OpenWithFlags() constructor, similar to Open() but allows to pass flags to perf_event_open(2). - HasRecord() to be able to read a sample without blocking.
