iov_iter: separate direction from flavour Instead of having them mixed in iter->type, use separate ->iter_type and ->data_source (u8 and bool resp.) And don't bother with (pseudo-) bitmap for the former - microoptimizations from being able to check if the flavour is one of two values are not worth the confusion for optimizer. It can't prove that we never get e.g. ITER_IOVEC | ITER_PIPE, so we end up with extra headache. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
