Very simple implementation of scull driver.
Reference LDD3. Chapter 3: Character Driver
Usage:
o $ make
o $ insmod scull.ko
o $ cat /proc/devinfo
o Note the major number corresponding to "scull"
o $ mknod /dev/scull0 -c <major number> <minor number>
This will create character file /dev/scull0
o Info of device can be seen in /proc/scullseq
Very detailed documentation of code coming soon.
