linux-next: build warning after merge of the nfsd tree

[Stephen Rothwell]

Hi,

After merging the nfsd tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/nfsd/nfs4xdr.c:241:1: warning: 'svcxdr_dupstr' defined but not used [-Wunused-function]
 svcxdr_dupstr(struct nfsd4_compoundargs *argp, void *buf, u32 len)
 ^~~~~~~~~~~~~

Introduced by commit

  e40d99e6183e ("NFSD: Clean up symlink argument XDR decoders")

The only remaining call is protected by CONFIG_NFSD_V4_SECURITY_LABEL.
