From: Yu Kuai <yukuai3@huawei.com>

The bdi_dev_name() should not be used in blk-cgroup code, because bdi is
not related at all, add a new helper to print device name directly from
gendisk. The helper can also fix that "unknown" will be printed for
hidden disks.

Yu Kuai (5):
  blk-cgroup: add a new helper blkg_print_dev_name()
  blk-iocost: use new helper blkg_print_dev_name()
  blk-throttle: use new helper blkg_print_dev_name()
  blk-iolatency: use new helper blkg_print_dev_name()
  blk-cgroup: use new helper blkg_print_dev_name()
