On tests adding and removing a remote port, calls to nvme_info would eventually show fewer target ports discovered than were present in the san. Additionally, the following error messages were seen: 6031 RemotePort Registration failed err: -116, DID x471301 There is a race condition that exists between the driver and the nvme transport on remote port unregister vs the confirmed deletion. It's possible that the driver may rediscover the remote port and reregister the remote port before a prior unregister delete callback was made (as it rebinded to the prior remoteport structure). However, the driver was coded to expect the callback before seeing the remote port again thus a new registration. The logic results in the driver having an invalid remoteport pointer set. Correct by tracking when waiting for the delete callback. In cases where the ndlp remoteport pointer is updated, it is only cleared when the wait has not been superceded by a prior registration.
