ext4_unlink:

	retval = dquot_initialize(dir);
	if (retval)
		return retval;
	retval = dquot_initialize(d_inode(dentry));
	if (retval)
		return retval;

f2fs_unlink:

	err = dquot_initialize(dir);
	if (err)
		return err;

ext4_rename

	retval = dquot_initialize(old.dir);
	if (retval)
		return retval;
	retval = dquot_initialize(new.dir);
	if (retval)
		return retval;

	/* Initialize quotas before so that eventual writes go
	 * in separate transaction */
	if (new.inode) {
		retval = dquot_initialize(new.inode);
		if (retval)
			return retval;
	}

f2fs_rename

	err = dquot_initialize(old_dir);
	if (err)
		goto out;

	err = dquot_initialize(new_dir);
	if (err)
		goto out;

ext4 call one more dquot_initialize than f2fs, I didn't look into this in
detail, but it's better to check that. :)
