Previously, the struct had a fixed-length array of\nsize MAX_BSETS which was indexed out-of-bounds for the dynamically-sized\niterators, which causes UBSAN to complain.\n\nThis patch uses the same approach as in bcachefs's sort_iter and splits\nthe iterator into a btree_iter with a flexible array member and a\nbtree_iter_stack which embeds a btree_iter as well as a fixed-length\ndata array."}],
