I have started to see this failure with some regularity:

116 is ESTALE.

During this test (on NFSv4.0) the client sends an OPEN(CLAIM_NULL) with
a name of "/" (confirmed via network capture). The Linux NFS server
rejects this OPEN with NFS4ERR_BADNAME due to a check in
fs/nfsd/nfs4xdr.c::check_filename().
