Subject: [PATCH v4 0/2] optimize the bfq queue idle judgment

Changes in V4:
 - fix a compile warning when CONFIG_BLK_CGROUP is not enabled.

Changes in V3:
 - Instead of tracking each queue in root group, tracking root group
 directly just like non-root group does.
 - remove patch 3,4 from these series.

Chagnes in V2:
 - as suggested by Paolo, add support to track if root_group have any
 pending requests, and use that to handle the situation when only one
 group is activated while root group doesn't have any pending requests.
 - modify commit message in patch 2

Yu Kuai (2):
  block, bfq: counted root group into 'num_groups_with_pending_reqs'
  block, bfq: do not idle if only one cgroup is activated
