Subject: Re: [v5 PATCH 6/6] mm: hwpoison: handle non-anonymous THP correctly
Date: Mon, 1 Nov 2021 12:38:44 -0700 [thread overview]
Message-ID: <CAPcxDJ5rgmyswPN5kL8-Mk2hk7MCjHXVy6pS50i=KQKzUGFHfA@mail.gmail.com> (raw)
A related bug but whose fix may belong to a separate series:
split_huge_page fails when invoked concurrently on the same THP page.
It's possible that multiple memory errors on the same THP get consumed
by multiple threads and come down to split_huge_page path easily.
Thanks,
-Jue
