16 Padata also supports multithreaded jobs, splitting up the job evenly while load
25 The first step in using padata to run serialized jobs is to set up a
26 padata_instance structure for overall control of how jobs are to be run::
39 jobs to be serialized independently. A padata_instance may have one or more
40 padata_shells associated with it, each allowing a separate series of jobs.
