When multiple entries are obtained consecutively, these entries are mostly stored adjacent to each other. this patch introduces a "last" parameter to cache the last opened buffer head, and reuse it when possible, which reduces the number of sb_bread() calls. When the passed parameter "last" is NULL, it means cache option is disabled, the behavior unchanged as it was.
