From 20138d6cb838aa01bb1b382dcb5f3d3a119ff2cb Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Wed, 17 Jul 2013 17:27:27 -0700 Subject: [PATCH] Drivers: hv: balloon: Initialize the transaction ID just before sending the packet Each message sent from the guest carries with it a transaction ID. Assign the transaction ID just before putting the message on the VMBUS. This would help in debugging on the host side. Signed-off-by: K. Y.
