Hi, In fs/char_dev.c the function alloc_chrdev_region() allows the user to allocate device number even when the count is 0.Something like this
retval=alloc_chrdev_region(&dev,0,0,"mychrdev"); This leads to a situation where callling unregister_chrdev_region() would not be able to free up the device number. Shouldn't there be a check which prevents this kind of allocation in the first place? -- Anubhav Rakshit -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [EMAIL PROTECTED] Please read the FAQ at http://kernelnewbies.org/FAQ
