Name:Ripoff of 'select_parent()'* search the list of submounts for a given mountpoint, and move any* shrinkable submounts to the 'graveyard' list.

Proto:static int select_submounts(struct mount *parent, struct list_head *graveyard)

Type:int

Parameter:

TypeParameterName
struct mount *parent
struct list_head *graveyard

2944  If Not heck if the mount 'mnt' can be unmounted successfully.*@mnt: the mount to be checked for unmount* NOTE: unmounting 'mnt' would naturally propagate to all* other mounts its parent propagates to.* Check if any of these mounts that **do not have submounts** Then
2945  list_move_tail - delete from one list and add as another's tail*@list: the entry to move*@head: the head that will follow our entry
