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.
Patches marked "[DO NOT MERGE]" are cherry-picked from linux-next (they are
not yet in drm-tip), to allow build and run CI on the patchset (it works only
on drm-tip tree).
Added CC to netdev as the only user of the library atm.
v2:
- replaced list_sort with ref_tracker_dir_stats, to avoid potentially
extensive sorting, if number of reports is expected to be big enough (???)
we can replace linear search in ref_tracker_dir_stats.stacks with binary
heap (min_heap),
- refactored gfp flags,
- fixed i915 handling of no-tracking flag.
