Andrew, could you please drop these ones: task-make-task-list-manipulations-rcu-safe-fix.patch task-make-task-list-manipulations-rcu-safe-fix-fix.patch Then we need this "patch" for de_thread: - list_add_tail_rcu(¤t->tasks, &init_task.tasks); + list_replace_rcu(&leader->tasks, ¤t->tasks); ... - list_del_init(&leader->tasks); Currently I don't know how the code looks in -mm tree, I lost the plot.
