From cdef511985374dd042a40bb32c1c346c2662c9dc Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Thu, 15 Jan 2015 15:21:19 +0100 Subject: KVM: fix sparse warning in include/trace/events/kvm.h sparse complains about include/trace/events/kvm.h:163:1: error: directive in argument list include/trace/events/kvm.h:167:1: error: directive in argument list include/trace/events/kvm.h:169:1: error: directive in argument list and sparse is right. Preprocessing directives in an argument of a macro are undefined behaviour as of C99 6.10.3p11. Lets use an indirection to fix this.
