Hi Johannes,

This link said that "When active pages are considered for eviction, they are first moved to the inactive list and unmapped from the address space of the process(es) using them. Thus, once a page moves to the inactive list, any attempt to reference it will generate a page fault; this "soft fault" will cause the page to be removed back to the active list."

Why I can't find the codes unmap during page moved from active list to inactive list?
