Chris Wilson db8337853b drm/i915/gem: Only revoke mmap handlers if active ... Avoid waking up the device and taking stale locks if we know that the object is not currently mmapped. This is particularly useful as not many object are actually mmapped and so we can destroy them without waking the device up, and gives us a little more freedom of workqueue ordering during shutdown. v2: Pull the release_mmap() into its single user in freeing the objects, where there can not be any race with a concurrent user of the freed object. Or so one hopes!
