I can't reproduce that. Do you see df errors each time you mount just created
reiser4 fs? Can you provide additional information about your system:
distro, libc which you used?

My hypothesysis is that libc statfs or df itself want to convert "free inodes"
result parameter which is __u64 to shorter data type. reiser4_statfs() sets
kstatfs->f_ffree to a large value which is close to 2^64.
