Date: Tue, 28 Aug 2012 13:59:13 +0200 From: Paolo Bonzini <pbonzini@...hat.com> To: linux-kernel@...r.kernel.org Cc: linux-scsi@...r.kernel.org, kvm@...r.kernel.org, jbottomley@...allels.com, "Richard W.M. Jones" <rjones@...hat.com> Subject: [PATCH for 3.6 2/3] virtio-scsi: initialize scatterlist structure for events From: Richard W.M. Jones <rjones@...hat.com> The sg struct for events is used without being initialized. This triggers a BUG_ON if CONFIG_DEBUG_SG is defined.
