cs->operrno is always 0 there. The value comes from nfs3svc_readdir_cbk where it
is 0 as well. The backtrace tells mewe go throigh:
nfs3svc_readdir_cbk 
io_stats_readdirp_cbk
dht_readdirp_cbk 
stripe_readdirp_cbk    <- errno == ENOENT is lost here
afr_readdir_cbk 
client3_3_readdirp_cbk 

In stripe_readdirp_cbk:
                STRIPE_STACK_UNWIND (readdir, frame, local->op_ret,
                                     local->op_errno, &local->entries, NULL);

Here local->op_errno = 0 and op_errno = 2 (ENOENT). I suspect op_ret is not set
correctly. I will explore further later.
