Subject: [PATCH] kabi fix for NFSv4.1: Don't rebind to the same source port when reconnecting to the server
Patch-mainline: never, kabi
References: bnc#1186264

The patch mentioned in subject adds a bit-field to 'struct rpc_xprt'.
This will use otherwise unused space in the struct, so it doesn't
actually change the size or offset of anything.
So it does not break the kabi in practice.

So hide the field from kabi checker.
