Step $1$: create an entry in proc file system named myproc when the kernel module is loaded; this entry myproc will be deleted when the kernel mode is deleted. You can use $ ls $/$proc$/$ to check whether it is existed. $($Hint: proc$\_$create$()$ and remove$\_$proc$\_$entry$()$ are needed.$)$ Step $2$: implement read$\_$proc and write$\_$proc function to read$/$write the proc file entry in Step $1.$ You need to add codes for allocating memory in init$\_$module and releasing the memory in cleanup$\_$module for the proc file entry. $($Hint: copy$\_$to$\_$user$()$ is needed for the read and copy$\_$from$\_$user$()$ is needed for write.$)$ To test your results, load the kernel module and there should be a new entry created under $/$proc$.$ Use cat and echo to verify and change the content of the new entry.
