Subject[PATCH 02/42] perf tools: Do not use __perf_session__process_events() directly
Date
It's only used for perf record to process build-id because its file
size it's not fixed at this time due to remaining header features.
However data offset and size is available so that we can use the
perf_session__process_events() once we set the file size as the
current offset like for now.
