If you allow that, then the process can use the old simple direct IB CM interface to put whatever it wants into the REQ private data.
The kernel uCM module needs to verify that the SID is not used, but I'm waiting until a standard SID is defined before adding it. SDP has a similar issue, except its check could be added now, since the SID is well known.
