Subject: [PATCH v2 0/2] blk-iocost: add refcounting for iocg and ioc

From: Yu Kuai <yukuai3@...wei.com>

Changes in v2:
 - Instead add ioc_pd_offline(), and move operations for iocg from
 ioc_pd_free() to ioc_pd_offline(), use refcounting to fix the problem.

Yu Kuai (2):
  blk-iocost: add refcounting for iocg
  blk-iocost: add refcounting for ioc
