I don't think you need the error message. If we get a memory allocation
failure, there's already going to be a lot of spew in the logs from the
mm system. And if we do fail to allocate memory, we don't need to know
the logical block number or the nid -- it has nothiing to do with those;
the system simply ran out of memory.
