I'll give it another try, but it very quickly becomes #include hell. Anybody want to comment on the performance impact of making local_irq_* non-inline functions? christian _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
