More strictly it looks like a race between truncate_complete_page()/delete_from_page_cache() and the cancel_userptr woker. I haven't seen this since around commit 40313f0cd0b711a7a5905e5182422799e157d8aa Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Apr 5 15:00:00 2016 +0100 drm/i915/userptr: Hold mmref whilst calling get-user-pages so I'm going to assume that it helped! Or the changes in worker etc. |
