It +is a registry of allocated major device numbers, as well as the +recommended {\file /dev} directory nodes for these devices. + +The latest version of this list is included with the Linux kernel +sources in \LaTeX\ and ASCII form. In case of discrepancy, the +\LaTeX\ version is authoritative. + +This document is included by reference into the Linux Filesystem +Standard (FSSTND). The FSSTND is available via FTP from +tsx-11.mit.edu in the directory {\file +/pub/linux/docs/linux-standards/fsstnd}. + +To have a major number allocated, or a minor number in situations +where that applies (e.g.\ busmice), please contact me with the +appropriate device information. Also, if you have additional +information regarding any of the devices listed below, or if I have +made a mistake, I would greatly appreciate a note. When sending me +mail, please include the word ``device'' in the subject so your mail +won't accidentally get buried! + +Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga +platform only. Allocations marked (68k/Atari) apply to Linux/68k on +the Atari platform only. + +This document is in the public domain. The author requests, however, +that semantically altered versions are not distributed without +permission of the author, assuming the author can be contacted without +an unreasonable effort. + +In particular, please don't sent patches for this list to Linus, at +least not without contacting me first. + +I do not have any information about these devices beyond what appears +on this list. Any such information requests will be deleted without +reply. + +\section{Major numbers} + +\begin{devicelist} +\major{ 0}{}{ }{Unnamed devices (e.g. non-device mounts)} +\major{ 1}{}{char }{Memory
