I think the logic in adir_lookup is quite broken and it gets confused
because the first iteration half-worked. Try adding `1 ||' at the
begin of the if-condition so that branch is always taken.

That's weird. Doesn't the_fbuf get initialized to {NULL, -1, 0, 0} ?

The fileid being zero is bad and is probably a result of fcache_fhget
failing. Did you get any debug output from xfs while arlad was
creating the cache files?
