Re: [PATCH 2/3] block: make blkcg aware of kthread stored original cgroup info

Hello,

Several blkcg APIs are deprecated. After removing them, bio_blkcg is the
only API to get cgroup info for a bio. If bio_blkcg finds current task
is a kthread and has original css recorded, it will use the css instead
of associating the bio to current task.

Can you please separate out removal of unused APIs from modifications
of existing ones?  The patch is a bit confusing to follow.

Thanks.
