From 78389046f733564d5c2c94f0b8d6ff0cdae951d9 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 12 Mar 2013 10:12:37 -0400 Subject: [PATCH] nfsd4: warn on odd create_session state This should never happen. (Note: the comparable case in setclientid_confirm *can* happen, since updating a client record can result in both confirmed and unconfirmed records with the same clientid.) Signed-off-by: J.
