Subject: [Cluster-devel] [PATCH 2/8] iomap: update ki_pos a little later in iomap_dio_complete
Date: Wed, 31 May 2023 09:20:00 +0200 [thread overview]
Message-ID: <20230531072006.476386-3-hch@lst.de> (raw)
In-Reply-To: <20230531072006.476386-1-hch@lst.de>
Move the ki_pos update down a bit to prepare for a better common
helper that invalidates pages based of an iocb.
