26  * struct padata_priv - Represents one job
32  * @info: Used to pass information from the parallel to the serial function.
33  * @parallel: Parallel execution function.

47  * struct padata_list - one per work type per CPU
58 * struct padata_serial_queue - The percpu padata serial queue
71  * struct padata_cpumask - The cpumasks for the parallel/serial workers
73  * @pcpu: cpumask for the parallel workers.
82  * struct parallel_data - Internal control structure, covers everything
83  * that depends on the cpumask in use.
92  * @cpumask: The cpumasks in use for parallel and serial workers.
110  * struct padata_shell - Wrapper around struct parallel_data, its
117  * @list: List entry in padata_instance list.
127  * struct padata_mt_job - represents one multithreaded job
131  * @start: The start of the job (units are job-specific).
132  * @size: size of this node's work (units are job-specific).
135  * @min_chunk: The minimum chunk size in job-specific units.  This allows
140  * @numa_aware: Distribute jobs to different nodes with CPU in a round robin fashion.
154  * struct padata_instance - The overall control structure.
158  * @parallel_wq: The workqueue used for parallel work.
161  * @cpumask: User supplied cpumasks for parallel and serial works.
