I'm trying to create a test using tst_fs but it seems quite 
unpredictable. For example, if the given paths are located on a 
different mount, EXDEV is raised.
But we don't have any control on it and it can happen with literally 
anything (signalfd, memfd, devices, etc) on the SUT we are testing.

So that ends up skipping 90% of the provided file descriptors. I don't 
know if I really want to follow this direction.
