Subject: [PATCH 12/16] xen/evtchn: support more than 4096 ports
Date: Wed, 2 Oct 2013 18:14:57 +0100 [thread overview]
Message-ID: <1380734101-2991-13-git-send-email-david.vrabel@citrix.com> (raw)
In-Reply-To: <1380734101-2991-1-git-send-email-david.vrabel@citrix.com>
From: David Vrabel <david.vrabel@citrix.com>
Remove the check during unbind for NR_EVENT_CHANNELS as this limits
support to less than 4096 ports.
