Ming Lei 7838b46561 block: define bvec_iter as __packed __aligned(4) ... In commit 19416123ab ("block: define 'struct bvec_iter' as packed"), what we need is to save the 4byte padding, and avoid `bio` to spread on one extra cache line. It is enough to define it as '__packed __aligned(4)', as '__packed' alone means byte aligned, and can cause compiler to generate horrible code on architectures that don't support unaligned access in case that bvec_iter is embedded in other structures.
