From: Stefano Stabellini Date: Fri, 16 Jul 2010 16:30:19 +0000 (+0100) Subject: pvops: do not notify callers from register_xenstore_notifier X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=31de189f7d02da163f77d46a86d9e655a2d83124;p=linux-beck.git pvops: do not notify callers from register_xenstore_notifier Currently register_xenstore_notifier notifies the caller during the registration itself if xenstore is believed to be ready. This behaviour causes problems to PV on HVM guests, in which case callers should be notified by xenbus_probe only after the platform pci driver is loaded. We already make sure xenbus_probe is called at the right time, calling it either from device_initcall (PV case) or from the platform pci driver initialization (HVM case) so we don't need this additional notification.
