entry_count is used in update_one() for two purposes: 1. to skip through the number of processed entries in in-memory index 2. to record the number of entries this cache-tree covers on disk Unfortunately when CE_REMOVE is present these numbers are not the same because CE_REMOVE entries are automatically removed before writing to disk but entry_count is not adjusted and still counts CE_REMOVE entries. Separate the two use cases into two different variables. #1 is taken care by the new field count in struct cache_tree_sub and entry_count is prepared for #2.
