Subject: [PATCH] drm/i915: Insert cond_resched() into i915_gem_free_objects
Git-commit: f2be9d68334dbb4ab8a3aa40b1633e3f408c616b
Patch-mainline: v4.13-rc1
References: FATE#322643 bsc#1055900
As we may have very many objects to free, check to see if the task needs
to be rescheduled whilst freeing them.
