I have an app taking 2 arguments, both file pathnames, and with the
constraint that they must be on the same filesystem. I could not find a
system call or libc for that, and a look in GNU df sources showed an
incredibly complex code. Besides, it reads /etc/mtab which is *not* a
pseudo-file, hence not absolutely reliable.

I find it hard to believe that there is no clean API for finding the
filesystem of a file.

Any suggestions?

TIA
