H A D | ringbuf.c | 6032ebb5 Thu Mar 25 10:01:15 CDT 2021 Pedro Tammela <pctammela@gmail.com> libbpf: Fix bail out from 'ringbuf_process_ring()' on error
The current code bails out with negative and positive returns. If the callback returns a positive return code, 'ring_buffer__consume()' and 'ring_buffer__poll()' will return a spurious number of records consumed, but mostly important will continue the processing loop.
This patch makes positive returns from the callback a no-op.
