mentioned next-20170811 kernel and this one 4.11. Your original report
as a reply to this thread
http://lkml.kernel.org/r/201708072228.FAJ09347.tOOVOFFQJSHMFL@I-love.SAKURA.ne.jp
mentioned next-20170728. None of them seem to have this fix
http://lkml.kernel.org/r/20170807113839.16695-3-mhocko@kernel.org so let
