You can compile with the following Makefile:

KVERSION = $(shell uname -r)
obj-m = workQueue.o

all:
    make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules
clean:
    make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean

Insert the module by:

# sync; insmod workQueue.ko; sync

And see the logs:

# tailf /var/log/kern.log

EDIT: I just added the delayed version:
