From 5d18c1c2a9a74e0f966c257520b8b7f5136c87b3 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 19 Oct 2010 23:00:12 -0400 Subject: [PATCH] nfsd4: only require krb5 principal for NFSv4.0 callbacks In the sessions backchannel case, we don't need a krb5 principal name for the client; we use the already-created forechannel credentials instead. Some cleanup, while we're there: make it clearer which code here is 4.0- or sessions- specific. Signed-off-by: J.
