Oh, now I see - that's because dprintk() is a no-op inline nowadays. > --- a/xen/arch/x86/hvm/irq.c > +++ b/xen/arch/x86/hvm/irq.c > @@ -386,7 +386,8 @@ void hvm_set_callback_via(struct domain *d, uint64_t via) > > spin_unlock(&d->arch.hvm_domain.irq_lock); > > - dprintk(XENLOG_G_INFO, "Dom%u callback via changed to ", d->domain_id); > +#ifndef NDEBUG > + printk(XENLOG_G_INFO, "Dom%u callback via changed to ", d->domain_id); This won't compile without warnings due to the extra comma. The right solution here seems to be to clone Linux'es "continue" log level, and then make dprintk() avoid adding its prefix in that case.
