It looks to me like "df" is reporting the disk usage faithfully from
the numbers that statfs is giving it: 2971459 / 4120920 is 0.721,
which would mean 72% is free and 28% is in use. The Used and Avail
lines also seem to match the statfs call: e.g., 2971459 * 32768 B is
90.68 GiB. So, if these numbers are wrong, it's something wrong with
your kernel or file system code, not in "df" itself.
