参数：

类型参数名称
struct rb_root_cached *root
unsigned longstart
unsigned longlast
73  如果非rb_node则返回:NULL
73  node = ({
73  __mptr等于rb_node
73  循环
73  当0循环
73  __mptr减__builtin_offsetof(structanon_vma_chain, rb)
73  })
73  如果rb_subtree_last小于start则返回:NULL
73  leftmost = ({
73  __mptr等于rb_leftmost
73  循环
73  当0循环
73  __mptr减__builtin_offsetof(structanon_vma_chain, rb)
73  })
73  如果avc_start_pgoff(leftmost)大于last则返回:NULL
73  返回:__anon_vma_interval_tree_subtree_search(node, start, last)
