Subject: [RFC PATCH 02/11] pagemap: add mapping_clear_large_folios() wrapper
Date: Tue, 13 Dec 2022 18:29:26 +0100 [thread overview]
Message-ID: <20221213172935.680971-3-aalbersh@redhat.com> (raw)
In-Reply-To: <20221213172935.680971-1-aalbersh@redhat.com>
Add wrapper to clear mapping's large folio flag. This is handy for
disabling large folios on already existing inodes (e.g. future XFS
integration of fs-verity).
