Subject: [PATCH 2/2] mm/gup: Remove page_folio() in memfd_pin_folios()
Date: Tue, 29 Apr 2025 18:00:59 -0700	[thread overview]
Message-ID: <20250430010059.892632-3-vishal.moola@gmail.com> (raw)
In-Reply-To: <20250430010059.892632-1-vishal.moola@gmail.com>

We can get the folio directly from the folio batch, so remove the
unnecessary page_folio() call.
