Subject: [PATCH] xen: ensure that all event channels start off bound to VCPU 0
Date: Fri, 8 Oct 2010 17:00:57 +0100 [thread overview]
Message-ID: <1286553657-22110-1-git-send-email-ian.campbell@citrix.com> (raw)
All event channels startbound to VCPU 0 so ensure that cpu_evtchn_mask
is initialised to reflect this.
sizeof(cpu_evtchn_mask(0))==sizeof(unsigned long*) which is not
correct, use sizeof(struct cpu_evtchn_s) instead.
