Sorry for safelink crap. (Need to remember to use my own SMTP to circumvent 
it.)

I don´t really understand this one. If I would change fio´s default behavior, I 
bet scripts may break. I wouldn´t change the meaning of "k" anyway, but just 
of "kib" and "kb", but still if a script uses one of these, it would break.

Additionally I would need to patch fio source code as I am not aware of any 
other way to change this default behavior.

I decided that I won´t do that.

So unless any change in upstream I will do with the README approach.

However, likely after an initial fio 3.1 Debian package uploaded is done. I 
just asked my sponsor Sven Hoexter to review the package.

Hmm, interesting.

Thanks,
