Message-ID: <1258115870.6167.4.camel@johannes.local> Date: Fri, 13 Nov 2009 13:37:50 +0100 From: Johannes Berg <johannes@...solutions.net> To: LKML <linux-kernel@...r.kernel.org> Subject: [PATCH 2.6.32] ftrace: fix event format export For some reason the export of the event print format to userspace uses '#fmt' which breaks if the format string is anything but a plain string, for example if it is built with macros then the macro names are exported instead of their contents. Use "\"%s\"", fmt instead of "%s", #fmt to export the string and not the way it is built. Signed-off-by: Johannes Berg <johannes@...solutions.net> --- This is making the export of a bunch of events (only checked the wireless ones but those are all affected) unusable, so please apply to 2.6.32. include/trace/ftrace.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- wireless-testing.orig/include/trace/ftrace.h 2009-11-13 13:15:21.000000000 +0100 +++ wireless-testing/include/trace/ftrace.h 2009-11-13 13:34:03.000000000 +0100 @@ -159,7 +159,7 @@ #undef __get_str #undef TP_printk -#define TP_printk(fmt, args...)
