But the Big BG code is not in the mainline kernel yet, and while the
64-bit code probably isn't getting used by anyone other than the ext4
developers, if it is going to be assumed by the BIG_BG code, we need
to get the Big BG format changes locked down and the Big BG code
merged into mainline ASAP. If we can't get it done soon, we will need
to add a flag, since otherwise users will get confused about whether
or not thier kernel will support a filesystem that has big blockgroups
enabled.
