2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Joerg Roedel commit c79ee4e466dd12347f112e2af306dca35198458f upstream. This patch fixes a bug in the overlap function which returned true if one region ends exactly before the second region begins. This is no overlap but the function returned true in that case.
