Hooked Sys_open issue, hanging and loading forever - c

Question

I am working on a project in which we have hooked the system open call. When a user attempts to open a file we want sys_open to check the given path against a file which contains file paths. If the given file path is contained in that file we want to stop them from opening the file. This is our module:
#include <linux/module.h> /* Needed by all kernel modules */
#include <linux/kernel.h> /* Needed for loglevels (KERN_WARNING, KERN_EMERG, KERN_INFO, etc.) */
#include <linux/init.h> /* Needed for __init and __exit macros. */
#include <linux/unistd.h> /* sys_call_table __NR_* system call function indices */
#include <linux/fs.h> /* filp_open */
#include <linux/slab.h> /* kmalloc */
#include <asm/paravirt.h> /* write_cr0 */
#include <asm/uaccess.h> /* get_fs, set_fs */
#include <linux/xattr.h>
#include <linux/dcache.h> /*dentry*/
#include <linux/namei.h>

I am confused as to what exactly is going wrong here and would very much appreciate some input! Thanks.
When I run the dmesg command this is the output:
