warning would also show up on all old kernels that don't even support


lockdown and then don't have the file. So would you suggest this message

Thanks, but I did not suggest to show the warning in any system without the
lockdown file. I mean if test getting FAIL on the no 'lockdown' file
system, then could consider throwing a warning as a hint.
And this could be achieved in the test case but not the library.

For indicating the 'lockdown' file exist or no-exist, the 'TINFO' is enough.
