Subject: [PATCH 11/26] 9p: Use alternative invalidation to using launder_folio
Date: Thu, 28 Mar 2024 16:34:03 +0000
Message-ID: <20240328163424.2781320-12-dhowells@redhat.com>
In-Reply-To: <20240328163424.2781320-1-dhowells@redhat.com>

Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Use writepages-based flushing invalidation instead of
invalidate_inode_pages2() and ->launder_folio().  This will allow
->launder_folio() to be removed eventually.
