Suppose processes a,b,c have a shared, anonymous page. All processes have this page present. Then the page for a is swapped out. Then b and c exit unexpectedly, after making changes to the page. When and if 'a' has the page swapped back in, what mechanism guarantees that it will see the changes made by b and c? Where specifically in the code, in what functions, does it reside for kernel 2.5? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
