I hope "struct kstate_image_pid" with several Sure pid namespaces are anonymous, but we will give each an 'objref' valid only for a checkpoint image, and store the relationship between pid namespaces based on those objrefs.

But this clone_pid is only for task_struct's pids. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
