Currently, to fix device following the write failure of one or more devices during btrfstune -m|M, we rely on the kernel's ability to reassemble devices, even when they possess distinct fsids. Kernel hinges combinations of metadata_uuid and generation number, with additional cues taken from the fsid and the BTRFS_SUPER_FLAG_CHANGING_FSID_V2 flag. This patch adds this logic to btrfs-progs. In complex scenarios (such as multiple fsids with the same metadata_uuid and matching generation), user intervention becomes necessary to resolve the situations which btrfs-progs can do better.
