From 9d093e2958baf76154d1008339f594f798a52790 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Thu, 29 Sep 2011 13:31:21 -0400 Subject: [PATCH] xen/events: BUG() when we can't allocate our event->irq array. In case we can't allocate we are doomed. We should BUG_ON instead of trying to dereference it later on.
