A bit of further investigation:

I'm currently not passing EXT2_FLAG_64BITS when opening the
filesystem.  Passing this flag fixes the issue, so I'm going to do
that (are there any downsides?)

It seems like a non-64-bit-compatible bitmap was being created, and
that doesn't have the bitmap->bitmap_ops field initialized because
gen_bitmap.c doesn't use this field.  Somehow, though, we end up
calling a function in gen_bitmap64.c which requires that this field be
defined.
