I didn't notice them before trying to enable metadata_csum feature.

On the other hand, enabling metadata_csum feature was pretty much the 
first thing I've made after booting to 3.5 kernel on this system, so it 
could be it changed something.


Also, when I do:

	dumpe2fs -h /dev/sda1|grep metadata_csum

I don't see metadata_csum feature anywhere.
