Same was with bonding when we started integration in OFED 1.2 but 
eventually we succeeded to make it work

We will enhance the patches once we get Roland's feedback

Yes we are

RDS - patches were reviewed by the RDS developers in the rds list.
SDP - Jim sent patches for keepalive. Zcopy will be sent when ready

There are101 patches in OFED 1.2, and I don't think it harmed anyone.

Note that most of the patches are code that will make it to kernel 2.6.24.
So the only way to avoid many patches is to change OFED 1.3 base kernel 
to 2.6.24
I suggest we will wait and see if we want to do it once 2.6.24 is out.
