    Abdul has noticed that reading sysctl vm.numa_zonelist_order
    read will never terminate. This is because of
    http://lkml.kernel.org/r/20170714080006.7250-2-mhocko@kernel.org
    where the reading side doesn't update ppos and so the reader will
    never get 0. Return back to proc_dostring which does all the necessary
    stuff.

I have added that to linux-next for tomorrow.
