I think it is just missing
commit 56de210245487ef1f1416c8ec9e581ebdd0d32ec

drbd: convert to idr_alloc()
Convert to the much saner new idr interface.
I'll post an updated 10/18 right away.
This RfC batch was produced from a tree
based more-or-less on your for-3.9-drivers, I think.
We will rebase to your for-3.10/drivers shortly,
and then also post an additional batch of general fixes.
