There is no need for such a comment.

Isn't it easier to get path with $(losetup -l | grep tmp | awk '{print $6}')

I would name each parameter ($1,$2,...) in the begining of the function 
as of make them more informative.
Or use "while getopts; do".

Don't need 'else' after return.

May be it would be better to call mkswap_test() without such wrappers 
and the for loop in the end.
