From 43b51ead3f752a3935116e5b1a94254b8573734f Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Fri, 7 Aug 2009 10:33:22 +0800 Subject: tracing/filters: Add __field_ext() to TRACE_EVENT Add __field_ext(), so a field can be assigned to a specific filter_type, which matches a corresponding filter function. For example, a later patch will allow this: __field_ext(const char *, str, FILTER_PTR_STR); Signed-off-by: Li Zefan LKML-Reference: <4A7B9272.6050709@cn.fujitsu.com> [ Fixed a -1 to FILTER_OTHER Forward ported to latest kernel. ] Signed-off-by: Steven Rostedt --- kernel/trace/trace_export.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'kernel/trace/trace_export.c') diff --git a/kernel/trace/trace_export.c b/kernel/trace/trace_export.c index 7087530..029a91f 100644 --- a/kernel/trace/trace_export.c +++ b/kernel/trace/trace_export.c @@ -158,7 +158,8 @@ __attribute__((section("_ftrace_events"))) event_##call = { \ #define TRACE_FIELD(type, item, assign) \ ret = trace_define_field(event_call, #type, #item, \ offsetof(typeof(field), item), \ - sizeof(field.item), is_signed_type(type)); \ + sizeof(field.item), \ + is_signed_type(type), FILTER_OTHER); \ if (ret) \ return ret; @@ -166,7 +167,7 @@ __attribute__((section("_ftrace_events"))) event_##call = { \ #define TRACE_FIELD_SPECIAL(type, item, len, cmd) \ ret = trace_define_field(event_call, #type "[" #len "]", #item, \ offsetof(typeof(field), item), \ - sizeof(field.item), 0); \ + sizeof(field.item), 0, FILTER_OTHER); \ if (ret) \ return ret; @@ -174,7 +175,8 @@ __attribute__((section("_ftrace_events"))) event_##call = { \ #define TRACE_FIELD_SIGN(type, item, assign, is_signed) \ ret = trace_define_field(event_call, #type, #item, \ offsetof(typeof(field), item), \ - sizeof(field.item), is_signed); \ + sizeof(field.item), is_signed, \ + FILTER_OTHER); \ if (ret) \ return ret; -- cgit v1.1
