Unfortunately, statfs in Linux does not return a filename. From statfs(2):

       The Linux statfs was inspired by the 4.4BSD one (but they  do  not  use
       the same structure).

In fact, struct statfs does not contain f_mntfromname or anything equivallent 
on Linux.

So I think it would be necessary to use statfs, only on *BSD (or if struct 
statfs contains f_mntfromname).

Thanks,
Okuji
