Subject: [PATCH v3 08/20] mm/rmap: pass vma to __folio_add_rmap()
Date: Mon,  3 Mar 2025 17:30:01 +0100	[thread overview]
Message-ID: <20250303163014.1128035-9-david@redhat.com> (raw)
In-Reply-To: <20250303163014.1128035-1-david@redhat.com>

We'll need access to the destination MM when modifying the mapcount
large folios next. So pass in the VMA.
