Heya, So I did a trimmed export of the patch from repository pointed out, and I have a comment about the config change below. I'm pretty sure i probably got the headers wrong, so sorry if i break threading with this email.

I would prefer not to change the config option name or text, and only change the depends. Cause ext4 driver in fact can be used for ext2/3, and can be used for ext2 or ext3 system mounts. The fact that there isn't an ext3 module anymore, doesn't change ext4 driver. I presume this option will remain even when both ext2 and ext3 drivers get dropped, such that one can toggle off ext2/3 portions of ext4 driver. Or am I wrong? -- Regards, Dimitri.
