C programming: My code is not running correctly and I amsure what's wrong. Please help. I have provided a screenshot andeverything below.

Assignment:

• Design a kernel module that creates a /proc filenamed /proc/jiffies that reports the current valueof jiffies when the /proc/jiffies file is read,such as with the command

  cat /proc/jiffiesBe sure to remove /proc/jiffies when the module isremoved.

Source Code:

jiffies.c

/* This function is called when the module is loaded. */

int proc_init(void)

{

/* creates the /proc/jiffies entry */

proc_create(PROC_NAME, 0666, NULL, &proc_ops);

return 0;

}

/* This function is called when the module is removed. */

void proc_exit(void)

{

/* removes the /proc/jiffies entry */

remove_proc_entry(PROC_NAME, NULL);

}

/* This function is called each time /proc/jiffies is read*/

ssize_t proc_read(struct file *file, char __user *usr_buf,size_t count, loff_t *pos)

{

int rv = 0;

char buffer[BUFFER_SIZE];

static int completed = 0;

if (completed) {

completed = 0;

return 0;

}

completed = 1;

rv = sprintf(buffer, "%lu", jiffies);

/* copies kernel space buffer to user space usr buf */

copy_to_user(usr_buf, buffer, rv);

return rv;

}
