    Bug #61341 buf_LRU_insert_zip_clean can be O(N) on LRU length · bedad622
    Marko Mäkelä authored
    The buf_pool->zip_clean list is only needed for debugging, or for
    recomputing buf_pool->page_hash when resizing the buffer pool. Buffer
    pool resizing was never fully implemented. Remove the resizing code,
    and define buf_pool->zip_clean only in debug builds.
    
    buf_pool->zip_clean, buf_LRU_insert_zip_clean(): Enclose in
    #if defined UNIV_DEBUG || UNIV_BUF_DEBUG.
    
    buf_chunk_free(), buf_chunk_all_free(), buf_pool_shrink(),
    buf_pool_page_hash_rebuild(), buf_pool_resize(): Remove (unreachable code).
