Subject: [RFC v2 1/4] mm: rename huge_zero_page_shrinker to huge_zero_folio_shrinker
Date: Thu, 24 Jul 2025 16:49:58 +0200 [thread overview]
Message-ID: <20250724145001.487878-2-kernel@pankajraghav.com> (raw)
In-Reply-To: <20250724145001.487878-1-kernel@pankajraghav.com>
From: Pankaj Raghav <p.raghav@samsung.com>
As we already moved from exposing huge_zero_page to huge_zero_folio,
change the name of the shrinker to reflect that.
No functional changes.
Suggested-by: David Hildenbrand <david@redhat.com>
