Subject: [PATCH 2/6] mm: pagewalk: don't check vma in walk_page_range_novma()
Date: Mon, 22 Aug 2022 15:00:47 +0200 [thread overview]
Message-ID: <21585888.EfDdHjke4D@devpool047> (raw)
In-Reply-To: <3200642.44csPzL39Z@devpool047>
Directly call walk_pgd_range() as that is everything that will actually
happen in __walk_page_range() besides checking if the vma is set.
