Submit a screenshot of the three terminal windows demonstrating that you have
implemented mutex successfully. I have attached an example shot from me below.
The three windows should be as follows:
Terminal 1: Displaying output of the kernel log (tail -f /var/log/kern.log -n 5), which
shows module insertion/init message, open message, and the being used
message.
Terminal 2: Showing that you ran sudo insmod hello.ko and then sudo ./test (don’t
type anything in response to the prompt, leave it there)
Terminal 3: Showing that you tried running sudo ./test again but were not able to
complete the program (since terminal 2 is currently using it).
