Yes, but I've written incorrect values, sorry. It's a little bit higher,
a run of my program outputs this on 2.6.24-19-generic (ubuntu 8.04.1):

expected 11778 files, but readdir reports 11779
expected 11862 files, but readdir64 reports 11863

And on 2.6.18-92.1.6.el5 (rhel 5.2):
expected 72922 files, but readdir reports 72923
expected 73131 files, but readdir64 reports 73132

The testcase is here: <http://www.unet.univie.ac.at/~a9100884/readdir.c>
