I am trying to open a shm file for data sharing between kernel and user process. Below is my kernel module code. Sys log output indicates that no errors were encountered. Once the module is loaded, I don't see the file that I'm trying to create in /dev/shm. What am I doing wrong?

Code:
#include <linux/module.h>
#include <linux/init.h>
#include <linux/kernel.h>
#include <linux/fs.h>
#include <linux/shmem_fs.h>

static int __init moduleLoader(void) {
    struct file *shfile;

    printk(KERN_INFO "shkmod is loading...\n");

    shfile = shmem_file_setup("MyShmFile",sizeof(int),0);
    printk("shmem_file_setup returned %p\n",shfile);
    if (IS_ERR(shfile))
        printk("shmem_file_setup returned error.\n");
    printk("shfile is: %s\n", shfile->f_path.dentry->d_name.name);

    printk(KERN_INFO "shkmod is done loading.\n");
    return 0;
}

static void __exit moduleUnloader(void) {
    printk(KERN_INFO "shkmod was unloaded.\n");
    return;
}

module_init(moduleLoader);
module_exit(moduleUnloader);

Here is the output in the sys log:
