Hi Christoph, here are the patches again. Reviewed and tested internally with DASD as well as DASD labeled virtblk devices. So if you agree with the two patches I have no objection against an inclusion. v3->v4: - merged patches - use symbol_get instead of kallsyms_lookup_name - add some comments and some cleanup Christoph Hellwig (1): dasd: refactor dasd_ioctl_information Stefan Haberland (1): s390/dasd: remove ioctl_by_bdev calls MAINTAINERS | 1 + block/partitions/ibm.c | 24 ++++++++--- drivers/s390/block/dasd_ioctl.c | 76 ++++++++++++++++++++++++--------- include/linux/dasd_mod.h | 9 ++++ 4 files changed, 85 insertions(+), 25 deletions(-) create mode 100644 include/linux/dasd_mod.h -- 2.17.1
