Hi all,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/linux/kernel.h:15,
from include/linux/list.h:9,
from include/linux/module.h:12,
from block/bfq-iosched.c:116:
block/bfq-iosched.c: In function 'bfq_set_next_ioprio_data':
block/bfq-iosched.c:4980:5: error: implicit declaration of function 'bdi_dev_name'; did you mean 'blkg_dev_name'? [-Werror=implicit-function-declaration]
4980 | bdi_dev_name(bfqq->bfqd->queue->backing_dev_info),
| ^~~~~~~~~~~~

Caused by commit

0f6438fca125 ("bdi: use bdi_dev_name() to get device name")

I have applied the following patch for today.
