Subject: Re: [PATCH v2 0/2] mm: don't migrate folios containing hwpoisoned pages
Date: Tue, 27 Oct 2026 20:08:54 +0800 [thread overview]
Message-ID: <20261027120854.1213156-1-xiangzao@linux.alibaba.com> (raw)

The fallback check does not compile on x86_64. There,
folio_mc_copy() only catches a synchronous #MC at the copy, and
software-injected poison never triggers one. The bug was reproduced
and measured on x86_64, so I think the series is still needed on the
arch it was found on.
