mdadm thread count

In the arch wiki under 6.19 it gives an example:

echo 8 > /sys/block/md0/md/group_thread_cnt

But when I try that after creating an mdadm raid set, I get:

# echo 8 > /sys/block/md0/md/group_thread_cnt
-bash: /sys/block/md0/md/group_thread_cnt: Permission denied

When I check the contents of /sys/bock/md0/md/ there is no file present.

And, yes I created the md device as md0, it exists. Well, existed because I just removed it to test something else .

Do I need to do something to make that file appear to set thread count?
