I believe that Jason and I still disagree but...
   
Jason suggests that I implement this feature with netlink. This approach might have an advantage but if I understand it right this approach requires a patch also to some user application in order to take advantage of this patch.

Also, I think that there is a value for a virtual text file under debugfs to monitor rdma_cm connections easily and without any other special app besides 'cat' (just like in IPoIB). 

Finally, this implementation doesn't contradict  netlink implementation in the future (and it won't be the first time).

BTW, this feature was suggested several times (first under procfs and later under debugfs) and Jason is the only one that objected to the concept, other agreed that the place should be a file system and only had comments to the implementation itself and to these comments I already answered.
