The cache loader performs two tasks: inserting cache objects in inactivity list and evaluating total cache size. Reading just directory is enough for this purpose. Elimination of reading cache files saves at least one disk I/O operation per file. Preparation for elimination of reading cache files by cache loader: removing dependencies on the reading: *) cache node valid_sec and valid_msec are used only for caching errors; *) upstream buffer size can be used instead of cache node body_start.
