Subject: Re: [PATCH v2] mm/memory-failure: Support disabling soft offline for HugeTLB pages
Date: Thu, 20 Aug 2026 11:47:11 +0800	[thread overview]
Message-ID: <0d2fc2ab-333e-42a1-88a1-6bb85538cbb0@linux.alibaba.com> (raw)
In-Reply-To: <aMiu_Uku6Y5ZbuhM@hpe.com>

Hi Kyle,

Following up on this thread. The v2 patch once landed in akpm's mm
tree (9ae6eefa4b6b "mm/memory-failure: support disabling soft
offline for HugeTLB pages"), but that commit is now not reachable
from any branch, and mainline as of v7.3-rc1 still only has the 0/1
switch in /proc/sys/vm/enable_soft_offline.

The underlying issue discussed here is still unresolved for us:
firmware reporting per-rank corrected error thresholds via GHES
triggers soft offline of huge pages, which neither addresses the
failing rank nor is acceptable for workloads that rely on stable
hugetlb physical layouts.

Do you still plan to send a v3, e.g. with the disable-bitmask
layout Anshuman suggested upthread?

Thanks.
Shuai
