Oops, I missed the changelog for this patch.

-----
Add group or all event enabling syntax support to bconf2ftrace.sh.
User can pass a bootconfig file which includes

ftrace[.instance.INSTANCE].event.enable

and

ftrace[.instance.INSTANCE].event.GROUP.enable

correctly.
-----

Steve, should I update the patch and resend the series?

Thank you,
