+ * This is not completely implemented yet. The idea is to
+ * create a in-memory tree (like the actual /proc filesystem
+ * tree) of these proc_dir_entries, so that we can dynamically
+ * add new files to /proc.
+ *
+ * The "next" pointer creates a linked list of one /proc directory,
+ * while parent/subdir create the directory structure (every
+ * /proc file has a parent, but "subdir" is NULL for all
+ * non-directory entries).
+ *
+ * "get_info" is called at "read", while "fill_inode" is used to
+ * fill in file type/protection/owner information specific to the
+ * particular /proc file.
