Much as I don't really understand the changelog - or know which changes should be cherry-picked - it looks like they are NOT picking the necessary changes. Pretty much everything looks like the support structure round mdadm, and I had difficulty spotting any cherry-picked changes that were mdadm itself. Given that mdadm is known to be buggy, that's worrying. And it *should* be perfectly safe to just upgrade mdadm - it's backwards-compatible and a user-space program, so is not critical in any way towards correct system functionality. This is where I think cherry-picking rather than wholesale upgrading is a bad idea - I understand why cherry-picking is a good idea, but those reasons don't apply here. Cheers, Wol
