Subject: [PATCH v2 22/23] mm: rename CONFIG_MEMORY_BALLOON -> CONFIG_BALLOON

From: "David Hildenbrand (Red Hat)" <[email-masked]>
Date: Thu, 15 Jan 2026 10:20:12 +0100

Let's make it consistent with the naming of the files but also with the
naming of CONFIG_BALLOON_MIGRATION.

While at it, add a "/* CONFIG_BALLOON */".
