Yeah. Basically, if we create a btrfs filesystem with a 4k blocksize

and MIPS which have a page size larger than 4k.
What happens currently? Does the btrfs code detect the mismatch and
refuse to mount, or does it all go horribly wrong?

I recall hacking the mkfs.btrfs tool, testing it, and finding that the
filesystem wouldn't mount. I haven't created a non-hacked filesystem
on x86 and ported it to PPC verbatim yet, but the same should happen
there; it shouldn't crash the kernel.
