    libperf: Add PERF_RECORD_THROTTLE 'struct throttle_event' to perf/event.h · 003c66fe
    Jiri Olsa authored
    Move the PERF_RECORD_THROTTLE 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.
