Hi,
Appearance of ref_tracker library allows to drop custom solution for wakeref tracking used in i915 and reuse the library. For this few adjustements has been made to ref_tracker, details in patches. I hope changes are OK for original author.
The patchset has been rebased on top of drm-tip to allow test changes by CI.
Added CC to netdev as the only user of the library atm.
Regards Andrzej
