_for_alignment_only

int64_t btree_page_data::item_body::_for_alignment_only

We use 8 byte alignment instead of the required 4 for historical reasons at this point:

child

PageID btree_page_data::item_body::child

interior

struct { ... } btree_page_data::item_body::interior

item_data

char btree_page_data::item_body::item_data[2]

really of size item_len - sizeof(item_len):

really of size item_len - sizeof(item_len) - sizeof(child):

item_len

item_length_t btree_page_data::item_body::item_len

leaf

struct { ... } btree_page_data::item_body::leaf
