Because rq_qos only make sense for rq based device. Instead of fail
from sysfs configuration, make wbt sysfs dentry invisible directly.
This looks ok, bt I would be better to just have a separate attr
group just for blk-mq based devices?
Sounds good, I'll add a new attr_group that is only visible for rq based
device, I think following attr can be moved to this new group:
nr_requests,
rq_affinity,
scheduler,
wbt_lat_usec
Thanks,
