From f59174d7e5fb8bb530246003d373345b5b433ea0 Mon Sep 17 00:00:00 2001 From: Andrew Cooper Date: Sat, 2 Jul 2016 11:43:02 +0100 Subject: [PATCH] xen/trace: Turn the stub debugtrace_{dump,printk}() macros into functions 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.
