35  * "work area" in PAPR. Although callers are allowed to block while
36  * holding a work area, the amount of memory reserved for this purpose

63  * rtas_work_area_free() - Release a work area.
64  * @area: Work area descriptor as returned from rtas_work_area_alloc().
66  * Return a work area buffer to the pool.
