This only affects 4.1/4.2 mounts if the server has delegations enabled or is a pNFS configuration. Even for those cases, the effect is mainly to only use slot 0 for callbacks, serializing all of them. There is a slight chance that callbacks will fail if the client performs them in a different order than received on the TCP connection. This patch fixes the problem. Found during a recent IETF NFSv4 testing event. --=20 You are receiving this mail because: You are the assignee for the bug.=
