Subject: [PATCH v2 0/4] optimize the bfq queue idle judgment

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 (4):
  block, bfq: add support to track if root_group have any pending
    requests
  block, bfq: do not idle if only one cgroup is activated
  block, bfq: add support to record request size information
  block, bfq: consider request size in bfq_asymmetric_scenario()
