Subject: [PATCH] gNFS: NFS segfaults with nfstest_posix tool
Problem:
nfs3_stat_to_fattr3() missed a NULL check.
FIX:
(1) Added a NULL check.
(2) In all fop cbk path, if the op_ret is -1 and op_errno is 0,
then handle it as a special case. Set the NFS3 status as
NFS3ERR_SERVERFAULT instead of NFS3_OK.
(3) The other component of FIX would be in DHT module and
is on the way.
