[Xen-devel] Why change from notify_via_evtchn to notify_remote_via_irq?
I noticed this change in the latest changeset. Any reason for doing this? Notify_via_evtchn seems to work fine for me. Thanks, Xin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
