[PATCH 0/9] drm/i915: use ref_tracker library for tracking wakerefs

[Andrzej Hajda]

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
