From e5d6f33abe9da025d3d891367f93d084e8c74bf5 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Mon, 28 Mar 2011 16:44:40 +0200 Subject: [PATCH] drbd: Change how the initial packets are called The first packets exchanged when a connection is established are referred to as P_HAND_SHAKE_S and P_HAND_SHAKE_M in the code, followed by P_HAND_SHAKE packets. To avoid confusion between these two unrelated things, call the initial packets P_INITIAL_DATA and P_INITIAL_META.
