From: Tzvetomir (VMware) Stoyanov <tz.stoyanov@xxxxxxxxx> In order to be consistent with the other libtracefs APIs, the char **tracefs_tracers(const char *tracing_dir); function is changed to accept NULL pointer as valid input argument. If NULL is passed, the tracers of the top instance are returned.
