SubjectPlans to obsolete register_chrdev()?
Hello,

In Linux 2.6, character device driver developers are supposed to use
alloc_chrdev_region() and cdev_add() instead of register_chrdev(). See
http://lwn.net/images/pdf/LDD3/ch03.pdf or http://lwn.net/Articles/126808/ .

However, in 2.6.16, there are still *very few* uses of cdev_add().
Compare http://lxr.free-electrons.com/ident?i=cdev_add to
http://lxr.free-electrons.com/ident?i=register_chrdev .

Are there plans to officially obsolete register_chrdev() (in particular
through Documentation/feature-removal-schedule.txt)?

Unless register_chrdev() is supposed to stay, I'll be glad to
participate in converting character driver code. In particular, would
updateds to drivers/chars/mem.c file be welcome?

Cheers,

Michael.
