Re: [PATCH v2 3/3] sgi-gru: Use __get_user_pages_fast in atomic_pte_lookup

[Christoph Hellwig]

I think the atomic_pte_lookup / non_atomic_pte_lookup helpers
should simply go away.  Most of the setup code is common now and should
be in the caller where it can be shared.  Then just do a:

        if (atomic) {
                __get_user_pages_fast()
        } else {
                get_user_pages_fast();
        }

and we actually have an easy to understand piece of code.
