[Xen-devel] [PATCH 2/2] xen/trace: Turn the stub debugtrace_{dump, printk}() macros into functions

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

This allows printf format checking to be performed, and for
debugtrace_printk() to evaluate its arguments, even if debugtrace is disabled
at compile time.

No intended change.
