close 534470 4.2-1 thanks Hi,
after reading through the messages, my take on it is: * if the admin start using newer kernels 'by accident' with e.g. a rescue system and then revert back to the old kernel on the system, this is obviously very anoying and understandably worrysome if the array gets converted to the new format. (jftr, in my professional opinion, on servers, I would always use the same version of the distribution on the rescue system than I would use on the production system anyway) however, in agreement what upstream implied in the bug, I consider this the less "bad" case than to not ask anyone on upgrades to manually migrate their arrays, as this is happens all the time versus the other, quite niche, case. * since amd64/i386 is not affected, it originally concerned only a small amount of system in the first place. now, several releases and more than a decade later, almost anyone is on the new layout already anyway. given all of the above, this bug will not hit anyone in real world anymore and will almost certainly not retroactively fixed ever, hence closing the bug rather than to leave it open here.
