Please try adding this before sys_open...
/* this sys_open never succeeds, hence sys_close is not needed */
ret = sys_open((const char __user *)"/dev", O_RDWR, 0);
printk(KERN_WARNING "Unable to open /dev (%d)\n", ret);

* either it's EISDIR
* or ENOENT
in either case, more digging is needed, and if it means writing a namespace
