Get rid of the #ifdefery. This should be just:
bio_associate_blkcg(split, bio->bi_css);
Gah, I see that the bi_css member is only present for CONFIG_BLK_CGROUP.
I guess we'll have to live with the ifdef.
We have already tried to remove it, but it seems it would require other
major changes.
Thanks,
Paolo
