Strangely enough, a few of your replies didn't reach my inbox and I just found them in the web archives: https://www.spinics.net/lists/linux-rdma/msg97973.html, and https://www.spinics.net/lists/linux-rdma/msg98133.html I will add check to ibv_dereg_mr() to avoid calling ibv_ibv_dofork_range() for dmabuf case. Thanks a lot for bring this up again.
