But the client side patch is needed only if Avati's server (posix) fix is present. And that is present only in 3.5 and not 3.4 .The client can actually be fixed to be compatible with both old and new servers. We can change the errno from ESTALE to ENOENT before doing the GFID mismatch check in client_lookup_cbk.
But this will require a two hop upgrade. Is that normal/acceptable? Pranith
