Hi Christoph and Jens, here I have a different proposal how to remove the ioctl_by_bdev calls from the DASD device driver. The patch is tested and from my perspective OK to be integrated. If you find it acceptable please feel free to integrate it into your tree. Otherwise I am open for suggestions.
