Hi,

Yes I still have those patches lying around and I'd be happy to dust
them off and resend them. I don't have ext4 support. I'd be willing to
take a stab at ext4 once Al is happy with the VFS part unless someone
more familiar with ext4 wants to contribute that support.

Thanks for reviving interesting in this!
