[PATCH] s390: use normal switch statement for ioctls in dasd_ioctlc
Add an ->ioctl method to the dasd_discipline structure. This allows to apply the same kind of cleanups the last patch applied to dasd_ioctl.c to dasd_eckd.c (the only dasd discipline with special ioctls) aswell. Again lots of code removed. During auditing the ioctls I found two fishy return value propagations from copy_{from,to}_user, maintainers please check those, I've marked them with XXX comments.
