[PATCH] ext4: removesector_t bits check
Previously when in-kernel ext4 block type is sector_t, it's only 4 bits long under some 32bit arch (when CONFIG_LBD is not on). So we need to check the size of sector_t before we read 48bit long on-disk blocks to in-kernel blocks. These checks are unnecessary now as we changed the in-kernel blocks to unsigned longlong.
