There is no such thing as a single owner for a fd based resource like a RDMA_CM ID. The FD can be held by multiple processes. This is why the best you can do by storing PIDs at certain times is to constuct a creator_pid. Owner pid can only be determined by cross-referencing the inode of the FD that holds the ownership of the object to the processes that hold that FD.
