Are you still working with v1 of this patch set? I root-caused the rss counter issue and seg fault to the fact that next or prev may be expanded and I was using the new start/end on munmap() in the completion. This was fixed in subsequent patches. I've sent v4 recently, but will have to a v5 to back off the removal of arch_unmap() for PPC. ... Thanks, Liam
