365 1. 'A' is a shared mount and 'B' is a shared mount. A new mount 'C'
366 which is clone of 'A', is created. Its root dentry is 'a' . 'C' is

372 of 'A'.

405 new mount 'C' which is a clone of 'A' is created. Its root dentry is
407 slave mount of 'Z'. In other words 'A' and 'C' are both slave mounts of
408 'Z'. All mount/unmount events on 'Z' propagates to 'A' and 'C'. But
409 mount/unmount on 'A' do not propagate anywhere else. Similarly
