- 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.
