Subject: [PATCH v3 0/1] mm/memory-failure: don't allow to unpoison hw corrupted page
Date: Fri, 10 Jun 2022 19:46:45 +0800 [thread overview]
Message-ID: <20220610114646.162764-1-pizhenwei@bytedance.com> (raw)
v2 -> v3:
- David pointed out that virt_to_kpte() is broken(no pmd_large() test
on a PMD), so drop this API in this patch, walk kmap instead.
v1 -> v2:
- this change gets protected by mf_mutex
- use -EOPNOTSUPP instead of -EPERM
v1:
- check KPTE to avoid to unpoison hardware corrupted page
