system.

+Specifically explore the sections titled "CHAR and MISC DRIVERS", and
+"BLOCK LAYER" in the MAINTAINERS file to find the right maintainers
+to involve for character and block devices.

**** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
-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.
-
-I do, however, make a few requests about the nature of your report.
-This is necessary for me to be able to keep this list up to date and
-correct in a timely manner. First of all, *please* send it to the
-correct address... <device@lanana.org>. I receive hundreds of email
-messages a day, so mail sent to other addresses may very well get lost
-in the avalanche. Please put in a descriptive subject, so I can find
-your mail again should I need to. Too many people send me email
-saying just "device number request" in the subject.
-
-Second, please include a description of the device *in the same format
-as this list*. The reason for this is that it is the only way I have
-found to ensure I have all the requisite information to publish your
-device and avoid conflicts.
+Linux now has extensive support for dynamic allocation of device numbering
+and can use sysfs and udev (systemd) to handle the naming needs. There are
+still some exceptions in the serial and boot device area. Before asking
+for a device number make sure you actually need one.
-Third, please don't assume that the distributed version of the list is
-up to date. Due to the number of registrations I have to maintain it
-in "batch mode", so there is likely additional registrations that
-haven't been listed yet.
+To have a major number allocated, or a minor number in situations
+where that applies (e.g. busmice), please submit a patch and send to
+the authors as indicated above.
