Note: Fast path APIs don't support tracepoints because the APIs contains struct and enum, if adding tracepints will lead to chkincs failure. Signed-off-by: Chengwen Feng Acked-by: Morten Brørup --- v5: Only support control path APIs tracepoints. v4: Fix asan smoke fail. v3: Address Morten's comment: Move stats_get and vchan_status and to trace_fp.h. v2: Address Morten's comment: Make stats_get as fast-path trace-points.
