From 153e44d22fb5f98198f90fbf56e89b345e48534d Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 9 May 2007 02:34:52 -0700 Subject: [PATCH] knfsd: rpc: fix server-side wrapping of krb5i replies It's not necessarily correct to assume that the xdr_buf used to hold the server's reply must have page data whenever it has tail data. And there's no need for us to deal with that case separately anyway. Acked-by: "J.
