From 5c04c46aec16b3267d8fe03af886f2d41e448cd0 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 30 Jun 2006 01:56:19 -0700 Subject: [PATCH] knfsd: nfsd: mark rqstp to prevent use of sendfile in privacy case Add a rq_sendfile_ok flag to svc_rqst which will be cleared in the privacy case so that the wrapping code will get copies of the read data instead of real page cache pages. This makes life simpler when we encrypt the response. Signed-off-by: J.
