mce: a question about memory_failure_early_kill in memory_failure()

[Xishi Qiu]

/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?

Thanks,
