*実装 [#d629174e]
 /*
  * This is not completely implemented yet. The idea is to
  * create an in-memory tree (like the actual /proc filesystem
  * tree) of these proc_dir_entries, so that we can dynamically
  * add new files to /proc.
  *
  * parent/subdir are used for the directory structure (every /proc file has a
  * parent, but "subdir" is empty for all non-directory entries).
  * subdir_node is used to build the rb tree "subdir" of the parent.
