Subject: [PATCH 4/6] block: stop setting ->direct_IO
Date: Tue,  1 Aug 2023 19:21:59 +0200	[thread overview]
Message-ID: <20230801172201.1923299-5-hch@lst.de> (raw)
In-Reply-To: <20230801172201.1923299-1-hch@lst.de>

Direct I/O on block devices now nevers goes through aops->direct_IO.
Stop setting it and set the FMODE_CAN_ODIRECT in ->open instead.
