https://stackoverflow.com/questions/2771707/how-to-support-udev-in-a-kernel-module
I'm porting a linux kernel module. It used to create a device file for itself (using dirty hacks with syscalls from kernelspace), but now I want to do this in udev. Where can I find documentation on supporting udev in in kernel module? Note that module itself is not a device driver. It serves as a multiplexor for a set of drivers.

Dec 18, 2009 · Udev is the device manager for the Linux 2.6 kernel that creates/removes device nodes in the /dev directory dynamically. It is the successor of devfs and hotplug. It runs in userspace and the user can change device names using Udev rules. Udev depends on the sysfs file system which was introduced in the 2.5 kernel.Author: Unnikrishnan

udev executes entirely in user space, as opposed to devfs's kernel space. One consequence is that udev moved the naming policy out of the kernel and can run arbitrary programs to compose a name for the device from the device's properties, before the node is created; there, the whole process is also interruptible and it runs with a lower priority.License: GPLv2

This will work fine with dvb-kernel drivers in CVS but not with the 2.6.8.1 drivers. Do you have any time estimations when udev support would be included in the Linux kernel tree? Gerd Knorr's bttv fixes (which are necessary for the bt8x8 based DVB budget cards) have just been applied to Linus' Bitkeeper repository.

Note. This documentation is outdated. Udev on modern distributions auto-detect the DVB devices. TODO: change this document to explain how to make DVB devices persistent, as, when a machine has multiple devices, they may be detected on different orders, which could cause apps that relies on the device numbers to fail.
