Not really. The purpose is to register the device only if the ring is local. This information is not available to modules. However we could just move the whole xenbus ring setup into a "module". Or is there any reason for this to be in a postcore_initcall, even if it is only operational after a userspace process works? > > int xenstored_ready; > > > > +/* A flag to determine if xenstored is 'local' */ > > +#ifdef CONFIG_XEN_BACKEND > > +static int xenstored_local; > > bool? Well. The other flags are int also. > > + BUG(); > No way. A WARN, sure - but BUG() is way too intense for this. Okay.
