iov_iter: unify iterate_iovec and iterate_kvec The differences between iterate_iovec and iterate_kvec are minor: * kvec callback is treated as if it returned 0 * initialization of __p is with i->iov and i->kvec resp. which is trivially dealt with. No code generation changes - compiler is quite capable of turning left = ((void)(STEP), 0); __v.iov_len -= left; (with no accesses to left downstream) and (void)(STEP); into the same code.
