Oh! I forgot to tell you that the cleanerd process was not running. When
I mounted the NILFS2 filesystem the cleanerd daemon said:

nilfs_cleanerd[29534]: start
nilfs_cleanerd[29534]: cannot create cleanerd on /dev/loop0
nilfs_cleanerd[29534]: shutdown

I thought I might have an old utilities version and that could be because
of that (since the nilfs website was down I couldn't check), but now
I checked in the backup nilfs website that latest version is 2.0.12 and
I have that (Debian package), so I don't know why the cleanerd failed to
start in the first place.
