From e5b36783c6277d91e91380a971374b79f8162e9e Mon Sep 17 00:00:00 2001 From: Jane Chu Date: Wed, 1 May 2024 17:24:57 -0600 Subject: mm/madvise: add MF_ACTION_REQUIRED to madvise(MADV_HWPOISON) The soft hwpoison injector via madvise(MADV_HWPOISON) operates in a synchrous way in a sense, the injector is also a process under test, and should it have the poisoned page mapped in its address space, it should legitimately get killed as much as in a real UE situation.
