alloc_pid()的参数ns在没有开启CONFIG_PID_NS的情况下,都是一样的,即指向init_pid_ns 设置完pid struct后,调用idr_replace将此pid struct和alloc的pid作为一对mapping值保存起来: structpid *alloc_pid(structpid_namespace *ns) {structpid *pid;enumpid_type type;inti, nr;structpid_namespace *tmp;stru...
当一个Network Namespace被销毁时,物理设备会被自动移回init Network Namespace,即系统最开始的Namespace。 2-UTS命名空间与PID 关联
