I think we should fix this in md.c:state_store(). rdev_attr_store() applies
to all the files. Could you please look into this?

Hi Song,
I considered changing the return code in state_store, but if we do so -
it requires also changes in mdadm (to expect different errno). It will
be hard to guarantee that mdadm and kernel are in sync with each other.
I checked mdadm code - it looks like there are no other places that
expect EBUSY to be returned from other files related to rdev - that's
why I think that it is safe to change it in rdev_attr_store().
Thanks
Pawel
