That patch doesn't use idr_preload(). It looks like the issue is
introduced during linux-next merge of wq/for-3.10 and idr patches in
-mm. Stephen, can you please add idr_preload_end() to the merge
patch?
Once the idr patches land in Linus' tree, I'll resolve the conflict
from wq tree side.
Thanks.
