So the image has plenty of space:
root@genericarmv8:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 2.3G 961M 1.2G 45% /
root@genericarmv8:~#
but only 48 free inodes:
root@genericarmv8:~# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/root 34440 34392 48 100% /
ext3 image is much more sensible:
root@genericarmv8:~# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/root 293888 34392 259496 12% /
e
I understand that the E in OE is about embedded, but still only 48 free
inodes seems a bit too steep. I would presume the amount of free inodes
should be about the same for both ext3 and ext4.
Also fiddling with EXTRA_IMAGECMD_ext4 doesn't seem to have any effect,
so currently ext4 images are not very useful.

Try Robert Yang's patches which build ext4 using mkfs.ext4 and debugfs
rather than genext2fs:
