From: Yu Kuai <yukuai3@xxxxxxxxxx> 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() block/blk-cgroup-rwstat.c | 13 +++++++------ block/blk-cgroup.c | 19 ++++--------------- block/blk-cgroup.h | 13 ++++++++++++- block/blk-iocost.c | 23 ++++++++++++----------- block/blk-iolatency.c | 11 +++++++---- block/blk-throttle.c | 15 +++++---------- 6 files changed, 47 insertions(+), 47 deletions(-) -- 2.39.2
