Tetsuo Handa f75868e020 block: check minor range in device_add_disk() ... [ Upstream commit e338924bd0 ] ioctl(fd, LOOP_CTL_ADD, 1048576) causes sysfs: cannot create duplicate filename '/dev/block/7:0' message because such request is treated as if ioctl(fd, LOOP_CTL_ADD, 0) due to MINORMASK == 1048575. Verify that all minor numbers for that device fit in the minor range.
