Subject: "Setting filesystem feature 'metadata_csum' not supported" when trying
 to enable ext4 metadata checksums

With Linux 3.5, it should be possible to use ext4 metadata checksums; 
enabling of which should be made with the following command:

# tune2fs -O metadata_csum /dev/sda1
tune2fs 1.42 (29-Nov-2011)
Setting filesystem feature 'metadata_csum' not supported.

Running kernel 3.5, tried the latest e2fsprogs from git.

What am I missing here?
