| 2009-03-10 | trace_clock: fix preemption bug | Peter Zijlstra | |
| Using the function_graph tracer in recent kernels generates a spew of preemption BUGs. Fix this by not requiring trace_clock_local() users to disable preemption themselves.

| 2009-02-26 | tracing: implement trace_clock_*() APIs | Ingo Molnar | |
| Impact: implement new tracing timestamp APIs Add three 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 Make the ring-buffer use the local trace clock internally.
