From: Bryan Schumaker <bjschuma@xxxxxxxxxx>
This patch exports all the symbols needed by the v4 module in addition
to creating the module itself.
The module (nfs4.ko) will be created in the same directory as nfs.ko and
will be automatically loaded the first time you try to mount over NFS v4.
Signed-off-by: Bryan Schumaker <bjschuma@xxxxxxxxxx>
