Well actually not really, I went and cut out the exit_lazy_tlb stuff from the patch series, those are better to be untangled anyway. I think an earlier version had something in exit_lazy_tlb for the mm refcounting change but it's not required now anyway. I'll split them out and just work on the shoot lazies series for now, I might revisit exit_lazy_tlb after the dust settles from that and the current membarrier changes. I'll test and repost shortly. Thanks, Nick
