From aa38e9fc3ea804290efd3a39316d7f7e6c945800 Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Fri, 7 Aug 2009 10:33:02 +0800 Subject: tracing/filters: Add filter_type to struct ftrace_event_field The type of a field is stored as a string in @type, and here we add @filter_type which is an enum value. This prepares for later patches, so we can specifically assign different @filter_type for the same @type. For example normally a "char *" field is treated as a ptr, but we may want it to be treated as a string when doing filting.
