Node of zip_free list.

Member Data Documentation

◆ bpage

buf_page_t buf_buddy_free_t::bpage

Embedded bpage descriptor.

◆ bytes

byte buf_buddy_free_t::bytes[FIL_PAGE_DATA]

stamp[FIL_PAGE_ARCH_LOG_NO_OR_SPACE_ID] == BUF_BUDDY_FREE_STAMP denotes a free block.

If the space_id field of buddy block != BUF_BUDDY_FREE_STAMP, the block is not in any zip_free list. If the space_id is BUF_BUDDY_FREE_STAMP then stamp[0] will contain the buddy block size.

◆ size

ulint buf_buddy_free_t::size

size of the block

◆

union { ... } buf_buddy_free_t::stamp
