    perf record/report: Fix PID/COMM handling · df97992c
    Ingo Molnar authored
    Fix two bugs causing lost comm mappings:
    
     - initial PID is not 0 but getpid()
    
     - when we are unable to handle an mmap event, dont assume the event
       itself is broken - try to parse the stream. This way we wont lose
       comm events.
