Protect ut_total_allocated_memory with ut_list_mutex in

os_mem_alloc_large() and os_mem_free_large(). The lack of this mutex

exclude any memory allocated by these functions when

Implement buf_block_align() with pointer arithmetics, as it is in the

When setting the PAGE_LEVEL of a compressed B-tree page from or to 0,

compress the page at the same time. This is necessary, because the

column information stored on the compressed page will differ between

leaf and non-leaf pages. Leaf pages are identified by PAGE_LEVEL=0.

Originally, there were provisions in InnoDB for multiple insert

When Heikki Tuuri implemented multiple InnoDB tablespaces in
