From: Ramesh Thomas <ramesh.thomas(a)intel.com&gt; Grouped workqueues and engines rely on state stored in structures associated with groups. Initialize the groups at the time of device init so they are available when workqueues are enabled. Flags are used to ensure groups do not get initialized again if they are already initialized once.
