Your code doesn't match your patch description.

You've got new includes of:

<linux/fs.h>
<linux/proc_fs.h>
<linux/err.h>
<linux/kref.h>

and forward declarations of

struct proc_dir_entry;
struct file_operations;

As a general rule, I think it better to use includes
than use naked forward declarations.
