    mnt: On an unmount propagate clearing of MNT_LOCKED · 5d88457e
    Eric W. Biederman authored
    A prerequisite of calling umount_tree is that the point where the tree
    is mounted at is valid to unmount.
    
    If we are propagating the effect of the unmount clear MNT_LOCKED in
    every instance where the same filesystem is mounted on the same
    mountpoint in the mount tree, as we know (by virtue of the fact
    that umount_tree was called) that it is safe to reveal what
    is at that mountpoint.
