I actually mis-read your patch, I'm sorry.
You're consolidating two callers of this so I guess this is not so
problematic. I somehow ignored the first hunk in the patch.
You could still evaluate if it isn't worth to make it:
+static void blk_mq_clear_mq_map(struct blk_mq_tag_set *set)
+{
+ int cpu;
+
+ for_each_possible_cpu(cpu)
+ set->mq_map[cpu] = 0;
+}
and put it into 'include/linux/blk-mq.h'.
