[PATCH] drm/i915: Complete both freed-object passes before draining the workqueue

[PATCH] drm/i915: Complete both freed-object passes before draining the workqueue

[Chris Wilson]

The workqueue code complains viciously if we try to queue more work onto
the queue while attampting to drain it. As we asynchronously free
objects and defer their enqueuing with RCU, it is quite tricky to
quiesce the system before attempting to drain the workqueue. Yet drain
we must to ensure that the worker is idle before unloading the module.

Give the freed object drain 3 whole passes with multiple rcu_barrier()
to give the defer freeing of several levels each protected by RCU and
needing a grace period before its parent can be freed, ultimately
resulting in a GEM object being freed after another RCU period.

A consequence is that it will make module unload even slower.
