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 <lizf@cn.fujitsu.com> LKML-Reference: <4A7B9272.6050709@cn.fujitsu.com> [ Fixed a -1 to FILTER_OTHER Forward ported to latest kernel. ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
