Chris Wilson aadad82c08 drm/i915: Filter wake_flags passed to default_wake_function ... commit 20612303a0b45de748d31331407e84300c38e497 upstream. (NOTE: This is the minimal backportable fix, a full fix is being developed at https://patchwork.freedesktop.org/patch/388048/) The flags passed to the wait_entry.func are passed onwards to try_to_wake_up(), which has a very particular interpretation for its wake_flags. In particular, beyond the published WF_SYNC, it has a few internal flags as well. Since we passed the fence->error down the chain via the flags argument, these ended up in the default_wake_function confusing the kernel/sched.
