26  * struct padata_priv - Represents one job
31  * @seq_nr: Sequence number of the parallelized data object.
32  * @info: Used to pass information from the parallel to the serial function.

71  * struct padata_cpumask - The cpumasks for the parallel/serial workers
74  * @cbcpu: cpumask for the serial (callback) workers.

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
138  * @max_threads: Max threads to use for the job, actual number may be less
154  * struct padata_instance - The overall control structure.
159  * @serial_wq: The workqueue used for serial work.
161  * @cpumask: User supplied cpumasks for parallel and serial works.
