[PATCH] Define struct pspace
Define a per-container pid space object. And create one instance of this object, init_pspace, to define the entire pid space. Subsequent patches will provide/use interfaces to create/destroy pid spaces. Its a subset/rework of Eric Biederman's patch http://lkml.org/lkml/2006/2/6/285 .
