The reason to take care of this at framework level is to avoid changes to individual tests. The wrapper keys off of KSFT_* codes returned from tests. Please don't send TAP conversion patches like this one. The output from the commands will have duplicate messages. The reason tests return make -C tools/testing/tmp2 run_tests make kselftest TARGETS=tmp2 thanks, -- Shuah

Conform the layout, informational and status messages to TAP. No functional change is intended other than the layout of output messages. The test has infinite loop to read the value of status_str. Break the loop after getting the value once and finish the test.
