Daniel Vetter b838cbee0d drm/i915: Remove bogus locking check in the hangcheck code ... You can _never_ assert that a lock is not held, except in some very restricted corner cases where it's guranteed that your code is running single-threade (e.g. driver load before you've published any pointers leading to that lock). In addition the early return breaks a bunch of testcases since with highly concurrent hangcheck stress tests the reset fails to work and the test doesn't recover and time out. This regression has been introduced in commit b8d24a0656 Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Wed Jan 28 17:03:14 2015 +0200 drm/i915: Remove nested work in gpu error handling Aside: It is possible to check whether a given task doesn't hold a lock, but only when lockdep is enabled, using the lockdep_assert_held stuff.
