It was always possible to assign major device numbers dynamically. I think what Jinesh wants to point out that , the parameer _dev itself should not be used by driver developers. It is something that should be obvious for the developer and treated as a black-box , so to speak.
Yes, Exactly!
So is POSIX compiancy the ONLY reason the major and minor numebrs are present ?
This is what I'm also wondering. Does POSIX say that there need to be major and minor numbers - if it doesn't, then there's no problem in shifting towards a blackbox concept for it. Even if POSIX insists upon having device files in /dev, may be what we can do is that we can keep symbolic links inside the directory. The links may point to some entry in sysfs. I think managing symbolic links would be easier for udev than to create device nodes. But if the POSIX insists upon having device files with major,minor numbers in /dev directory, then I'm sorry for coining this idea. May be we have to wait some time till POSIX gets a revision.
