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

函数原型：static int select_submounts(struct mount *parent, struct list_head *graveyard)

返回类型：int

参数：

类型参数名称
struct mount *parent
struct list_head *graveyard
2922  this_parent等于parent
2924  found等于0
2926  repeat :
2927  next等于链表后项
2928  resume :
2929  当next不等于 list of children, anchored here 循环
2930  tmp等于next
2931  mnt等于list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(tmp, structmount, mnt_child)
2933  next等于链表后项
2934  如果非mnt_flags按位与MNT_SHRINKABLE的值则继续下一循环
2939  如果非链表为空则
2940  this_parent等于mnt
2941  转到:repeat
2944  如果非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**则
2945  链表项移动到尾部
2946  found自加
2952  如果this_parent不等于parent则
2953  next等于链表后项
2954  this_parent等于mnt_parent
2955  转到:resume
2957  返回:found
