| Subject: perf trace: Do not process PERF_RECORD_LOST twice |
| |
| commit 3ed5ca2efff70e9f589087c2013789572901112d upstream. |
| |
| We catch this record to provide a visual indication that events are |
| getting lost, then call the default method to allow extra logging shared |
| with the other tools to take place. |
| |
| This extra logging was done twice because we were continuing to the |
| "default" clause where machine__process_event() will end up calling |
| machine__process_lost_event() again, fix it. |
