H A D | trace_export.c | 75db37d2 Thu Mar 26 10:43:36 CDT 2009 Steven Rostedt <srostedt@redhat.com> tracing: add size checks for exported ftrace internal structures
The events exported by TRACE_EVENT are automated and are guaranteed to be correct when used.
The internal ftrace structures on the other hand are more manually exported. These require the ftrace maintainer to make sure they are up to date.
This patch adds a size check to help flag when a type changes in an internal ftrace data structure, and the update needs to be reflected in the export.
If a export is incorrect, then the only harm is that the user space tools will not know how to correctly read the internal structures of ftrace.
[ Impact: help prevent inconsistent ftrace format print outs ]
