A module that just does a printk and then refuses
to be inserted?  Insmod it every time you want a
test line.

#include <linux/module.h>
#include <linux/kernel.h>
MODULE_LICENSE("GPL");

int refuse(void)
{
    printk(KERN_WARNING "I'm a pointless module.  Hello log file!\n");
    return -1;
}

module_init(refuse);

/* to build modules outside the kernel tree:
Documentation/kbuild/modules.txt  */
