The new features of this release:

- Added TRACE_DEFINE_SIZEOF() which allows trace events that use
     sizeof() it the TP_printk() to be converted to the actual size such
     that trace-cmd and perf can parse them correctly.
 
   - Some rework of the TRACE_DEFINE_ENUM() such that the above
     TRACE_DEFINE_SIZEOF() could reuse the same code.
 
   - Recording of tgid (Thread Group ID). This is similar to how
     task COMMs are recorded (cached at sched_switch), where it is
     in a table and used on output of the trace and trace_pipe files.
 
   - Have ":mod:<module>" be cached when written into set_ftrace_filter.
     Then the functions of the module will be traced at module load.
 
   - Some random clean ups and small fixes.
