    libperf: Add PERF_RECORD_LOST_SAMPLES 'struct lost_samples_event' to perf/event.h · a2e254d8
    Jiri Olsa authored
    Move the PERF_RECORD_LOST_SAMPLES event definition into libperf's
    event.h header include.
    
    In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
    events to their generic '__u*' versions.
    
    Perf added 'u*' types mainly to ease up printing __u64 values
    as stated in the linux/types.h comment:
    
      /*
       * We define u64 as uint64_t for every architecture
       * so that we can print it with "%"PRIx64 without getting warnings.
       *
       * typedef __u64 u64;
       * typedef __s64 s64;
       */
    
    Add and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_' to
    ease up the reading and differentiate them from standard PRI*64 macros.
