Usama,

As I mentioned another TAP conversion patch from you  patch if the
following command gives you TAP, there is  no need to convert.

make -C tools/testing/tmp2 run_tests
make kselftest TARGETS=tmp2

kselftest framework lib.mk and runtests wrappers take care for
TAP. 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
