The class buf::Block_hint that was added in order to fix MDEV-23693 buf_pool.page_hash .
Originally, I was thinking that this function could be removed as part of rewriting the buffer pool resizing in MDEV-29445 btr_pcur_t::old_page_id to remember the page identifier where the persistent cursor position was stored, and pass this identifier to buf_page_optimistic_get() , which will have to perform a buf_pool.page_hash lookup anyway.
Furthermore, in btr_pcur_optimistic_latch_leaves() we had better look up the current page normally, and perform some tricks to prevent a deadlock when acquiring a latch on the previous page, if needed. This will also allow us to simplify the function btr_pcur_move_backward_from_page() .
