Subject: [PATCH 02/12] iomap: update ki_pos a little later in iomap_dio_complete
Date: Thu, 1 Jun 2023 16:58:54 +0200 [thread overview]
Message-ID: <20230601145904.1385409-3-hch@lst.de> (raw)
In-Reply-To: <20230601145904.1385409-1-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.
