Hi!

I would rather see the code cleaned up. Basically most of the exit(1)
calls are part of the option parsing code that should rather be
tst_brkm(TBROK, ...); Then there is a very few places that actually call
exit() that should either be tst_brkm(TBROK, ...) or tst_resm().

The worst part is that this define replaces exit() in the signal handler
as well which is not safe at all...

Or we can just get rid of the unfinished attempt to convert the testcase
to LTP test API. Or even try to sync with the version from xfstests that
has been cleaned up...
