/proc/sys/vm/memory_failure_early_kill 1: means kill all processes that have the corrupted and not reloadable page mapped. 0: means only unmap the corrupted page from all processes and only kill a process who tries to access it. If set memory_failure_early_kill to 0, and memory_failure() has been called. memory_failure() hwpoison_user_mappings() collect_procs() // the task(with no PF_MCE_PROCESS flag) is not in the tokill list try_to_unmap() If the task access the memory, there will be a page fault, so the task can not access the original page again, right?
