Thanx for the reply.

I see. Actually on my test system for v4.11-rc8, kthreadd, kworker, kswapd and others all stopped working due to the synchronize_rcu_expedited call from i915_gem_shrinker_count. It is definitly a show stopper for me as an i915 user.
It was a few weeks ago when you posted. It is a pity the fix was not merged before v4.11 comes out. I know v4.11 will appear soon. So I'd ask i915 developers, would you test Andrea Arcangeli's fix and release it as v4.11.1 as soon as possible?
