Hi Neil-

I'd like to reduce the amount of page allocation that NFSD does,
and was wondering about the release and reset of pages in
svc_xprt_release(). This logic was added when the socket transport
was converted to use kernel_sendpage() back in 2002. Do you
remember why releasing the result pages is necessary?
