Let's go further and have the API simply:

	inode_acl_release(inode);

with inode_acl_release looking something like:

	if (inode->i_acl && inode->i_acl != ACL_NOT_CACHED)
		acl_release(inode->i_acl);
	if (inode->i_default_acl && inode->i_default_acl != ACL_NOT_CACHED)
		acl_release(inode->i_default_acl);
