Add ":tracer" suffix support for the requires list, so that the testcase can list up the required tracer (e.g. function) to the requires list. For example, if the testcase requires function_graph tracer, it can write requires list as below instead of checking available_tracers. # requires: function_graph:tracer Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Reviewed-by: Tom Zanussi <zanussi@kernel.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
