Seems to work OK, but does two "leaving via shortcut" calls instead of one.
Why is that? This needs to be explained and then fixed.


  insmod ./procfsread.o    insert the module
  lsmod                    see if the modules has loaded
  tail /var/log/syslog     see module load message
  ls /proc/test            see if the file /proc/test is there

  cat /proc/test           read the procfile, watch count go up.
  cat /proc/test           read the procfile, watch count go up again.
  cat /proc/test           read the procfile, watch count go up again.
  tail /var/log/syslog     see module read messages
  rmmod procfsread         unload module
  lsmod                    see if the modules has unloaded
  less /var/log/syslog     see module unload message. Read all the
                            messages produced by this module.
