The original algorithm was suffering from an ABA race condition: A: fp = page_stack B: completely allocates the same page and writes into it some data A: unsuspecting, loads (invalid) next = fp->next B: finishes working with the page and returns it back to page_stack A: compare-exchange page_stack: fp => next succeeds and writes garbage to page_stack Fixed this by using an implicit spinlock in hot page allocator. |
