59d8053f1e1690 David Howells 2013-04-11 21 * This is not completely implemented yet. The idea is to
59d8053f1e1690 David Howells 2013-04-11 22 * create an in-memory tree (like the actual /proc filesystem
59d8053f1e1690 David Howells 2013-04-11 23 * tree) of these proc_dir_entries, so that we can dynamically
59d8053f1e1690 David Howells 2013-04-11 24 * add new files to /proc.

710585d4922fd3 Nicolas Dichtel 2014-12-10 26 * parent/subdir are used for the directory structure (every /proc file has a
710585d4922fd3 Nicolas Dichtel 2014-12-10 27 * parent, but "subdir" is empty for all non-directory entries).
710585d4922fd3 Nicolas Dichtel 2014-12-10 28 * subdir_node is used to build the rb tree "subdir" of the parent.
