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,
