Mike Christie 528ec5abe6 dm: pass dm stats data dir instead of bi_rw ... It looks like dm stats cares about the data direction (READ vs WRITE) and does not need the bio/request flags. Commands like REQ_FLUSH, REQ_DISCARD and REQ_WRITE_SAME are currently always set with REQ_WRITE, so the extra check for REQ_DISCARD in dm_stats_account_io is not needed. This patch has it use the bio and request data_dir helpers instead of accessing the bi_rw/cmd_flags directly. This makes the next patches that remove the operation from the cmd_flags and bi_rw easier, because we will no longer have the REQ_WRITE bit set for operations like discards.
