From: Tao Cui blk_queue_for_each_rl() was added by commit a051661ca6d1 ("blkcg: implement per-blkg request allocation") to iterate over the root request list and per-blkg request lists for the legacy (non-blk-mq) request allocation path. The request_list code, including q->root_rl from struct request_queue, was later removed in 2018 by commit db6d99523560 ("block: remove request_list code"). The macro definition left behind in the !CONFIG_BLK_CGROUP fallback branch of the private block/blk-cgroup.h header now references the removed q->root_rl field, and has no callers in-tree (it would fail to compile if expanded, so it cannot have any out-of-tree users either). Remove the dead stub.
