I think at one point Dave said that if you touch more than 1 filesystem with a series you should just CC linux-fsdevel and omit the individual filesystems? I realize that this series only touches ext2 and ext4 a little, but that's what I opted for. Is that sufficient to get to the rest of the XFS developers, or would you like a resend adding linux-xfs?
