Bryan Schumaker 6938867edb NFS: Remove bad delegations during open recovery ... I put the client into an open recovery loop by: Client: Open file read half Server: Expire client (echo 0 > /sys/kernel/debug/nfsd/forget_clients) Client: Drop vm cache (echo 3 > /proc/sys/vm/drop_caches) finish reading file This causes a loop because the client never updates the nfs4_state after discovering that the delegation is invalid. This means it will keep trying to read using the bad delegation rather than attempting to re-open the file.
