This is really a comment to the previous patch, but I only spotted it
here:  I think the right name is iov_iter_pin_pages, as bvec, kvec and
pipe aren't usually user pages.  Same as iov_iter_get_pages vs
get_user_pages.  Same for the _alloc variant.

Nit: the ant and the will still fit on the previous line.
