If you want to solve the problem sooner, then mail list is faster than kernel bugzilla. For your case, it's just a warning for unaligned device size, normally caused by older mkfs or older kernel. You can fix it by using "btrfs rescue fix-device-size <device>" on a unmounted fs, or use "btrfs resize <devid>:-4K <mnt>" to resize *each* device of your mounted fs. I'd prefer "btrfs rescue fix-device-size <device>" if you have the latest version of btrfs-progs, as it does not only fix the unaligned device size, but also fix your super block total bytes.
