From 8c974438085d2c81b006daeaab8801eedbd19758 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Thu, 21 Oct 2010 01:06:15 +0000 Subject: Revert c6537d6742985da1fbf12ae26cde6a096fd35b5c Backout the tipc changes to the flags int he subscription message. These changees, while reasonable on the surface, interefere with user space ABI compatibility which is a no-no. This was part of the changes to fix the endianess issues in the TIPC protocol, which would be really nice to do but we need to do so in a way that is backwards compatible with user space.
