Bruce,
Your commit below causes a new build warning in the kernel:
net/sunrpc/svc.c: In function 'svc_printk':
net/sunrpc/svc.c:1050:7: warning: unused variable 'buf'
which affects all ARM builds; it is the only warning in a lot of cases.
Please can you resolve this new warning using whatever method you feel
is most appropriate, thanks.

svcrpc: demote some printks to a dprintk
In general I'd rather random bad behavior on the network won't trigger a
printk.

Bah, these "unused variable" warnings for buffers unused in the
!RPC_DEBUG case keep popping up.
I guess I'll commit the following for 3.9.
--b.
