From 2ed5282cd9b44686a6e718269abb5c5cd332d8f1 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 12 Aug 2010 17:04:07 +1000 Subject: svcauth_gss: replace a trivial 'switch' with an 'if' Code like: switch(xxx) { case -error1: case -error2: .. return; case 0: stuff; } can more naturally be written: if (xxx < 0) return; stuff; Signed-off-by: NeilBrown Signed-off-by: J.
