      iov_iter: Separate type from direction and use accessor functions · aa563d7b
      David Howells authored
      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.

      iov_iter: Use accessor function · 00e23707
      David Howells authored
      Use accessor functions to access an iterator's type and direction.  This
      allows for the possibility of using some other method of determining the
      type of iterator than if-chains with bitwise-AND conditions.
