函数名称：This function populates subtree_max_size from bottom to upper* levels starting from VA point

函数原型：static __always_inline void augment_tree_propagate_from(struct vmap_area *va)

返回类型：void

参数：

类型参数名称
struct vmap_area *va
627  node等于 address sorted rbtree
630  当node循环
631  va等于rb_entry(node, structvmap_area, rb_node)
632  new_va_sub_max_size等于Gets called when remove the node and rotate.
640  如果 in "free" tree 恒等于new_va_sub_max_size则退出
643  in "free" tree 等于new_va_sub_max_size
644  node等于rb_parent( & address sorted rbtree )

insert_vmap_area_augment
merge_or_add_vmap_areaMerge de-allocated chunk of VA memory with previous* and next free blocks. If coalesce is not done a new* free area is inserted. If VA has been merged, it is* freed.
