Ah that's grand, I'm glad to have helped to improve things.
I'm not familiar with fanotify, however a quick look at fanotify_user.c 
suggests that a similar approach may be taken by modifying:

if(!fsn_mark) {
	...
}
else if (create) {
	return -EEXIST;
}

in both fanotify_add_vfsmount_mark() and fanotify_add_inode_mark()
