blkcg: restructure configuration printing
Similarly to the previous stat restructuring, this patch restructures conf printing code such that, * Conf printing uses the same helpers as stat. * Printing function doesn't require hardcoded switching on the config being printed. Note that this isn't complete yet for throttle confs. The next patch will convert setting for these confs and will complete the transition. * Printing uses read_seq_string callback (other methods will be phased out). Note that blkio_group_conf.iops[2] is changed to u64 so that they can be manipulated with the same functions. This is transitional and will go away later. After this patch, per-device configurations - weight, bps and iops - use __blkg_prfill_u64() for printing which uses white space as delimiter instead of tab. Signed-off-by: Tejun Heo <tj@kernel.org>
