Subject: [PATCH v5 07/28] mm: alloc_anon_folio: pass raw fault address to vma_alloc_folio
Date: Thu, 7 May 2026 18:22:48 -0400	[thread overview]
Message-ID: <6d63fef8150c92fcffde0742877fe18ccc3da59a.1778192416.git.mst@redhat.com> (raw)
In-Reply-To: <cover.1778192416.git.mst@redhat.com>

Now that vma_alloc_folio aligns the address internally, callers
no longer need to pre-align. Pass vmf->address directly.
