Doubt in dup_mmap()

Hi all,

	In the function dup_mmap() in kernel/fork.c, 

	file = tmp->vm_file;
	if (file) {
		struct inode *inode = file->f_dentry->d_inode;
		get_file(file);
		if(tmp->vm_flags & VM_DENYWRITE)
			atomic_dec(&inode->i_writecount);

	After this piece of code, shouldn't there be :
	
		else
			atomic_inc(&inode->i_writecount);

	as this is a read-write mapping ?
