This patch moves that to common code [1] and adds a\n-\u003egetgeo method to fill out the raw kernel hd_geometry structure. For many\ndrivers this means -\u003eioctl can go away now.\n\n[1] the s390 block drivers are odd in this respect. xpram sets -\u003estart\n to 4 always which seems more than odd, and the dasd driver shifts\n the start offset around, probably because of it\u0027s non-standard\n sector size.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Jens Axboe \u003caxboe@suse.de\u003e\nCc:
