2020-05-21s390/dasd: remove ioctl_by_bdev callsStefan Haberland1-0/+9
The IBM partition parser requires device type specific information only available to the DASD driver to correctly register partitions. The current approach of using ioctl_by_bdev with a fake user space pointer is discouraged. Fix this by replacing IOCTL calls with direct in-kernel function calls.
