upstream commit 66ec384ad3044d63c9726493a412a2ad5317eae5 Make sel_make_bools and sel_make_classes take the specific elements of selinux_fs_info that they need rather than the entire struct. This will allow a future patch to pass temporary elements that are not in the selinux_fs_info struct to these functions so that the original elements can be preserved until we are ready to perform the switch over.
