From 7d98d6ffab9bca18d610ec08cbd2b41b2911f315 Mon Sep 17 00:00:00 2001 From: Haiyang Zhang Date: Thu, 5 Aug 2010 19:30:01 +0000 Subject: staging: hv: Fixed the value of the 64bit-hole inside ring buffer commit e5fa721d1c2a54261a37eb59686e18dee34b6af6 upstream. Fixed the value of the 64bit-hole inside ring buffer, this caused a problem on Hyper-V when running checked Windows builds. Checked builds of Windows are used internally and given to external system integrators at times. They are builds that for example that all elements in a structure follow the definition of that Structure. The bug this fixed was for a field that we did not fill in at all (Because we do Not use it on the Linux side), and the checked build of windows gives errors on it internally to the Windows logs. This fixes that error.
