The patch that adds this check is d6ce9ad DEVONLY: nfs41: Do not free slot if retried while operation was in progress It was originally rejected (http://www.spinics.net/lists/linux-nfs/msg09562.html) due to noise regarding where nfs41_sequence_free_slot is called but that masked the real issue. Can you readily reproduce this? Can you debug also the server side to see if indeed the client retries the RPC while it is in progress on the server?
