[Xen-devel] [PATCH 04/25] argo: define argo_dprintk for subsystem debugging

[Christopher Clark <christopher.w.clark@xxxxxxxxx>]

A convenience for working on development of the argo subsystem:
toggling a local #define variable turns on just the debug messages
in this subsystem.

  printk("argo: " format, ## args )
