Re: [PATCH v16 01/18] tracing: Use arch_ftrace_regs() for ftrace_regs_*() macros

FYI, for anything to do with function hooks (fentry), the subject should be
"ftrace:" not "tracing:".

Tracing has to do with the tracing infrastructure, whereas ftrace is the
function hook infrastructure.

I just accepted the first two patches of this series and made the changes
to the subjects.

If a change is for function graph infrastructure specifically, you can use
"fgraph:" instead.
