D'oh. 4294967295 is what you get (instead of -1) if you interpret the
value correctly as unsigned long, which is obviously correct (types.h,
exim, and df -i agree). Thanks for the correction.
BTW if my memory does not trick me completely this is the second time
reiserfs has switched, it started with returning zero (yielding an
incompatibility with inn of this time) before it switched to returning
the big number.
