[PATCH 1/4] blk-cgroup: Remove unnecessary blk_ioprio_exit in blkcg_init_queue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Function blk_ioprio_init only alloc blkg_policy_data which will be freed
in blkg_destroy_all, so no blk_ioprio_exit is called when blk_throtl_init
is failed in blkcg_init_queue. Also blk_ioprio_exit is not called in
blkcg_exit_queue for the same reason. Just remove blk_ioprio_exit to
keep behavior consistent.
