In particular, would > updates to the drivers/chars/mem.c file be welcome? No answer in 3 days... Does anyone know whether register_chrdev is really supposed to go? If register_chrdev is obsolete, it would be nice to start migrating existing character drivers to alloc_chrdev_region() and cdev_add(), and I will be glad to help.
