I removed the tar file of the whole directory (see previous note), but I
added three new tar files for three new kernel module examples. The xtime
example is very close to the solution to lab 5-nutt4 kernel modules lab, but
without the loops and with all the debugging prints to the syslog. I'll tar
up this whole directory, but put it up a level in the handouts directory.

The tar file includes all the code in this directory for you to download
into your slackware2.4 virtualbox kernel and get working. After you get
this code working you still need to extend the code to complete the Nutt 4
lab as specified on pp103-104. Specifically, this means you need to
recode the procfsread.c program so it returns a string of the xtime
and you need to write and run the test program sketched on pp103-104.

Testing on the Slackware 2.4 kernel posted in the kerel images handout
directory.

hello/              OK   This directory is just a simple C program.

mod-hello/          OK  First Module program right from the LKMPG for 2.4 Kernel
mod-procfsregister/ OK  Registers a simple proc file read that doesn't do much
mod-procfsread/     OK  Registers a proc file read that increments a count on read

mod-syscall-240/    OK  A system call module replacing an unused 2.4 system call

Transferred from Sancho laptop with the Gentoo 2.4 kernel. Needs to be 
recompiled and tested.

These programs work on a Gentoo 2.4 kernel, but have not yet been tested
on the Slackware 2.4 kernel posted in the kernel images handout directory.
