cregit-Linux how code gets into the kernel

Release 4.12 include/linux/trace_clock.h

Directory: include/linux


 * 3 trace clock variants, with differing scalability/precision
 * tradeoffs:
 *  -   local: CPU-local trace clock
 *  -  medium: scalable global clock with some jitter
 *  -  global: globally monotonic, serialized clock
