Hi,
Kirill noticed that the following piece of code from md_alloc(dev, name)
is dead:
if (name && dev)
/*
* Creating /dev/mdNNN via "newarray", so adjust hold_active.
*/
mddev->hold_active = UNTIL_STOP;
md_alloc() is always called with either dev == 0 or name == NULL.
Judging from the commit that added this code:

md: allow creation of mdNNN arrays via md_mod/parameters/new_array
and from the comment, it seems should be "if (!name && dev)".
But that would also change ->hold_active for created-by-open md devices,
and I'm not sure whether that would be a desirable change or not.
