nfsd41: control nfsv4.1 svc via /proc/fs/nfsd/versions
Support enabling and disabling nfsv4.1 via /proc/fs/nfsd/versions by writing the strings "+4.1" or "-4.1" correspondingly. Use user mode nfs-utils (rpc.nfsd option) to enable. This will allow us to get rid of CONFIG_NFSD_V4_1 [nfsd41: disable support for minorversion by default] Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: J.
