Subject: [PATCH v2 2/5] 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.
