[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.
