[PATCH v2 27/27] drm/dp_mst: Add topology ref history tracking for debugging
...I've found this incredibly useful
for debugging topology refcount errors.
Since this has the potential to be somewhat slow and loud, we add an
expert kernel config option to enable or disable this feature,
CONFIG_DRM_DEBUG_DP_MST_TOPOLOGY_REFS.
Changes since v1:
* Don't forget to destroy topology_ref_history_lock

[PATCH v5 14/14] drm/dp_mst: Add topology ref history tracking for debugging

for debugging topology refcount errors.
Since this has the potential to be somewhat slow and loud, we add an

Changes since v1:
* Don't forget to destroy topology_ref_history_lock
Changes since v4:
* Correct order of kref_put()/topology_ref_history_unlock - we can't
unlock the history after kref_put() since the memory might have been
freed by that point
* Don't print message on allocation error failures, the kernel already
does this for us

[PATCH v2 00/27] DP MST Refactors + debugging tools + suspend/resume reprobing
This is the large series for adding MST suspend/resume reprobing that
I've been working on for quite a while now. In addition, I:
- Refactored and cleaned up any code I ended up digging through in the
process of understanding how some parts of these helpers worked.
- Added some debugging tools along the way that I ended up needing to
figure out some issues in my own code
