My HO is that termination of init task should terminate all the other tasks in pspace. Otherwise you have too select some one else to be child_reaper and actually there is no good choice here as no one except init is going to wait() for children. p.s. can you enumerate these patches please? since I failed to find where struct pspace was introduced... imho in previous patch set? was that patch set already commited to -mm?
