Now writing to the kernel queue is supported.
To do this, look for a file in /sys/devices/virtual/char_dev_class/simpleCharDriver
called "fifo". Echo anything you want into it, and then to see that it's been written into
kernel memory, cat /dev/simpleCharDriver.
A mutex to prevent reading from multiple processes would be useful,
as well as reading only one entry at a time from the queue (calling cat now reads the entire queue).
More soon.
