Subject: [PATCH v1 06/17] mm/rmap: pass vma to __folio_add_rmap()
Date: Thu, 29 Aug 2024 18:56:09 +0200 [thread overview]
Message-ID: <20240829165627.2256514-7-david@redhat.com> (raw)
In-Reply-To: <20240829165627.2256514-1-david@redhat.com>
We'll need access to the destination MM when modifying the total mapcount
of a non-hugetlb large folios next. So pass in the VMA.
