blkcg: implement blkg_prfill_[rw]stat_recursive() blkg_prfill_[rw]stat_recursive() collect the specified [rw]stats from the target policy_data and its descendants and print it. They can be used to make stat printing hierarchical. blkg_for_each_descendant_pre() and blkg_[rw]stat_collect() are added to implement the new prfill functions. While at it, function comment is added to __blkg_lookup() which is now also used by the for_each macro. Signed-off-by: Tejun Heo <tj@kernel.org>
