The series looks good to me know. How do we want to handle it?  I think
we need a special branch somewhere (maybe in the block or mm trees?)
so that we can base the other iov_iter work from John on it.  Also
Al has a whole bunch of iov_iter changes that we probably want on
the same branch as well, although some of those (READ vs WRITE fixups)
look like 6.1 material to me.
