Subject: [v3 1/4] mm: hugetlb_vmemmap: Use nid of the head page to reallocate it
Date: Fri, 25 Aug 2023 12:18:33 +0100 [thread overview]
Message-ID: <20230825111836.1715308-2-usama.arif@bytedance.com> (raw)
In-Reply-To: <20230825111836.1715308-1-usama.arif@bytedance.com>
If tail page prep and initialization is skipped, then the "start"
page will not contain the correct nid. Use the nid from first
vmemap page.
