Subject: [PATCH v3 06/12] mm: hugetlb_vmemmap: rename vmemmap_remap_pte() to vmemmap_optimize_pte()
Date: Wed, 4 Nov 2026 10:35:04 +0800 [thread overview]
Message-ID: <20261104023510.260766-7-songmuchun@bytedance.com> (raw)
In-Reply-To: <20261104023510.260766-1-songmuchun@bytedance.com>
Both optimization and restoration update vmemmap PTEs by remapping them,
so "remap" does not identify the callback's role. Use "optimize" for the
optimization callback to match "restore" and make the two directions
explicit and consistent.
No functional change intended.
