Having only this struct describing an proc entry, i have no idea on how to detect when the file is closed. For this i expect to register a callback function but where and how?

struct proc_dir_entry {
	unsigned int low_ino;
	unsigned short namelen;
	const char *name;
	mode_t mode;
	nlink_t nlink;
	uid_t uid;
	gid_t gid;
	unsigned long size;
	struct inode_operations * proc_iops;
	struct file_operations * proc_fops;
	get_info_t *get_info;
	struct module *owner;
	struct proc_dir_entry *next, *parent, *subdir;
	void *data;
	read_proc_t *read_proc;
	write_proc_t *write_proc;
	atomic_t count;		/* use count */
	int deleted;		/* delete flag */
};

Thanks,
Matthias
