Another option would be to change prepare_device() so that it works fine
with NULL tst_fs pointer, then we could simply do:

	prepare_device(tst_test->filesystems);


And for that we would have to do something like this:

diff --git a/lib/tst_test.c b/lib/tst_test.c
index b49c248ae..ec6deea9b 100644
--- a/lib/tst_test.c
