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? -- Chuck Lever
