iov_iter: Separate type from direction and use accessor functions 2018-10-23T23:41:07+00:00 David Howells dhowells@redhat.com 2018-10-19T23:57:56+00:00 aa563d7bca6e882ec2bdae24603c8f016401a144 In the iov_iter struct, separate the iterator type from the iterator direction and use accessor functions to access them in most places. Convert a bunch of places to use switch-statements to access them rather then chains of bitwise-AND statements. This makes it easier to add further iterator types. Also, this can be more efficient as to implement a switch of small contiguous integers, the compiler can use ~50% fewer compare instructions than it has to use bitwise-and instructions. Further, cease passing the iterator type into the iterator setup function. The iterator function can set that itself. Only the direction is required.
