Subject: releasing result pages in svc_xprt_release()
Date: Fri, 29 Jan 2021 16:19:13 +0000 [thread overview]
Message-ID: <811BE98B-F196-4EC1-899F-6B62F313640C@oracle.com> (raw)
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?
