-Rename drm_atomic_commit
------------------------
-
-The KMS framework uses two slightly different definitions for the ``state``
-concept. For a given object (plane, CRTC, encoder, etc., so
-``drm_$OBJECT_state``), the state is the entire state of that object. However,
-at the device level, ``drm_atomic_commit`` refers to a state update for a
-limited number of objects.
-
-The state isn't the entire device state, but only the full state of some
-objects in that device. This is confusing to newcomers, and
-``drm_atomic_commit`` should be renamed to something clearer like
-``drm_atomic_commit``.
-
-In addition to renaming the structure itself, it would also imply renaming some
-related functions (``drm_atomic_commit_alloc``, ``drm_atomic_commit_get``,
-``drm_atomic_commit_put``, ``drm_atomic_commit_init``,
-``__drm_atomic_commit_free``, etc.).
