I want to write a Device driver. And I am facing some problem. Problem-: I have created a raw partition and it has major no 22. And I want to register this major no (22) for my device driver. But it gives error like "register_blkdev : cannot get major no 22".
There are certain major numbers which are free to be used, and you are advised to stick onto them unless you intend to keep your driver in the kernel tree. If you wish so, you will have to get major numbers assigned to you. Go through Documentation/devices.txt for more info. HTH. Om. -- Kernelnewbies: Help each other learn about the Linux kernel.
