These two new members will act the same as the existing local lists, @useless and @list in build_backref_tree(). Currently build_backref_tree() is only executed serially, thus moving such local list into backref_cache is still safe. Also since we're here, use list_first_entry() to replace a lot of list_entry() calls after !list_empty(). Signed-off-by: Qu Wenruo <wqu@xxxxxxxx>
