Subject: [PATCH 3/3] mm: Rename vma_pgoff_address back to vma_address
Date: Thu, 28 Mar 2024 22:58:29 +0000	[thread overview]
Message-ID: <20240328225831.1765286-4-willy@infradead.org> (raw)
In-Reply-To: <20240328225831.1765286-1-willy@infradead.org>

With all callers converted, we can use the nice shorter name.
Take this opportunity to reorder the arguments to the logical
order (larger object first).
