For subpage metadata validation check, there are some differences:
- Read must finish in one bvec
Since we're just reading one subpage range in one page, it should
never be split into two bios nor two bvecs.
- How to grab the existing eb
Instead of grabbing eb using page->private, we have to go search radix
tree as we don't have any direct pointer at hand.
