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

391 of 'A'.

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

892 A example propagation tree looks as shown in the figure below.

905 In the above figure A,B,C and D all are shared and propagate to each
906 other. 'A' has got 3 slave mounts 'E' 'F' and 'G' 'C' has got 2 slave
911 A's ->mnt_share links with the ->mnt_share of 'B' 'C' and 'D'
913 A's ->mnt_slave_list links with ->mnt_slave of 'E', 'K', 'F' and 'G'
917 'E', 'K', 'F', 'G' have their ->mnt_master point to struct vfsmount of 'A'
