Subject: [PATCH v6 0/4] mm, hwpoison: improve handling workload related to hugetlb and memory_hotplug
Date: Fri, 7 Oct 2022 10:07:02 +0900 [thread overview]
Message-ID: <20221007010706.2916472-1-naoya.horiguchi@linux.dev> (raw)
Hi,
This patchset tries to solve the issue among memory_hotplug, hugetlb and hwpoison.
In this patchset, memory hotplug handles hwpoison pages like below:
- hwpoison pages should not prevent memory hotremove,
- memory block with hwpoison pages should not be onlined.
Changes in this version:
- applied comments for previous versions (thank you, reviewers),
- fixed a few build errors (sorry for making noises on linux-next),
- unpoison_memory() properly cancels per-memblk hwpoison counter,
- rebased onto akpm/mm-unstable on Oct 4.
Thanks,
Naoya Horiguchi
