Ah, that's because the patch didn't go through Pekka's slab tree but went 
into -mm instead so we have to wait for another -mm.  However, the traces 
from linux-next-20140204 that you provided indicate it's the same problem 
and should be fixed with that patch, so let's wait for another mmotm to be 
released.
