EDIT: If myinc_value is an N-digit integer, I get the first N/2 bytes of the msg buffer back in user space. So if myinc_value = 48, cat /dev/my_inc yields 4. If myinc_value = 489324, cat /dev/my_inc yields 489. This behavior persists even after I added the following code directly after the while loop, to nul-terminate the user-space b...

Since the Linux kernel is GPL and not LGPL I suppose that it is illegal to link proprietary code to it. How does the industry circumvents this? I would expect that the GPL license will force any developer to release under GPL driver and/or kernel module. Maybe I am confused and implementing a new module is not really linking against the...
