Subject: Maximum number of directories

Hi all,
What is the maximum number of directories ext4 can hold in a tree layout with
a depth of ~160 and each directory node having then a couple to couple dozen
subdirectories?
I was creating such a (crazy?) tree and hit -ENOSPC at ~31 million directories
created in total with df showing only 40% use:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/data 477277612K 177766152K 275621952K 40% /data
Some lines from tune2fs made me think it should hold more, but obviously I was
mistaken? Or it is a bug?
Inode count: 29868032
Free inodes: 29848131
Regards,
Tvrtko
