I thought of a simple example. 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?
