Chris Wilson 5774506f15 drm/i915: Borrow our struct_mutex for the direct reclaim ... If we have hit oom whilst holding our struct_mutex, then currently we cannot reap our own GPU buffers which likely pin most of memory, making an outright OOM more likely. So if we are running in direct reclaim and already hold the mutex, attempt to free buffers knowing that the original function can not continue until we return. v2: Add a note explaining that the mutex may be stolen due to pre-emption, and that is bad.
