Yes, it's too long. LTP_FS_TYPE_DEBUG sounds best to me, but no strong opinion
about it.

If we agree we want this, we can consider to use some switch instead or print
this variable in help output (-h), with other variables from
https://github.com/linux-test-project/ltp/wiki/User-Guidelines.

I do use it as well, but it's I wanted to have way to debug single filesystem
without having to recompile (easier on embedded or non-intel platforms run via
some frameworks).

Kind regards,
