something i was curious about way back when -- given that register_chrdev_region() and alloc_chrdev_region() allow one to specify a range of minor numbers desired that doesn't necessarily have to start at zero, is there a way from user space to see what those numbers are after the device registration is complete?

/sys/dev/char/ after the driver has registered those minor numbers with the driver core is your best bet. hope this helps, greg k-h
