raw_open and hdev_open contain the same basic logic. Add a new raw_open_common helper containing the guts of the open routine and call it from raw_open and hdev_open. We use the new open_flags field in BDRVRawState to allow passing additional open flags to raw_open_common from both. Signed-off-by: Christoph Hellwig <hch@lst.de>
