This (and other) existing function prototypes however use u8 pointers. With the existing code, a caller may use an u8 pointer. By using the new macro, there is now an implicit cast from u8 to u128 pointers. So, in theory the current use cases of these functions could use data pointers that may not be aligned to 128 bit boundaries. How did you conclude that the now implicit casting from u8 to u128 is correct in all use cases for all modified function prototypes? Thanks a lot. > -asmlinkage void camellia_ctr_32way(struct camellia_ctx *ctx, u8 *dst, > - const u8 *src, le128 *iv); > - > -asmlinkage void camellia_xts_enc_32way(struct camellia_ctx *ctx, u8 *dst, > - const u8 *src, le128 *iv);
