number

Simple hello-world-like Linux kernel driver that allows to create devices similar to /dev/zero but with arbitrary byte emmitted.

Building

make all

Usage

As superuser execute:

insmod number.ko

After that you can create devices invoking

./make_number.sh zeroes 48

That will make /dev/zeroes that emmit zeroes ("0" symbol).

TODO

Add mmap support (looks non-trivial for me now).
