Hi,

today I experimented with hard links on btrfs and by this used all available inode space of a file.
Interestingly if this happens even a rename of such an filename to  an _equal length_ filename
fails:

arnd@kallisto:/mnt/btrfs/tmp$ mv a b
mv: cannot move `a' to `b': Too many links

Is this expected behavior?
There should be no reason to let this particular case fail?

Best regards,
Arnd
