It's actually related; I had this in the commit message:
"
This introduces a new situation where a blocked device is being unplugged.
Decrement the group->recovery_cnt accordingly.
"

So, it was not needed prior to this patch: it wouldn't fix anything
if applied before, and it would be a bit odd to apply/fix after.

It's a small three-line change, so I think folding it in is okay?

Thanks
