Linux 3.2 with eglibc 2.13.

The same happens with a freshly compiled 8.16, and it seems
that df uses statfs instead of statvfs:
# src/df --version
df (GNU coreutils) 8.16
[...]
# strace -v src/df -h ~/tmp/mnt
[...]
stat("/home/nikratio/tmp/mnt", {st_dev=makedev(0, 23), st_ino=1,
st_mode=S_IFDIR|0755, st_nlink=1, st_uid=1000, st_gid=1000, st_blksize=131072,
st_blocks=0, st_size=0, st_atime=2012/05/04-22:13:30,
st_mtime=2012/05/04-22:13:18, st_ctime=2012/05/04-22:13:18}) = 0
statfs("/home/nikratio/tmp/mnt", {f_type=0x65735546, f_bsize=81920,
f_blocks=104857, f_bfree=104854, f_bavail=104854, f_files=1000000,
f_ffree=999994, f_fsid={0, 0}, f_namelen=0, f_frsize=10485760}) = 0
[...]
Any idea what might be happening here?
Best,
