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. -- Steve On Tue, 15 Oct 2024 10:28:43 +0900 "Masami Hiramatsu (Google)" <mhiramat@xxxxxxxxxx> wrote: > From: Masami Hiramatsu (Google) <mhiramat@xxxxxxxxxx> > > Since the arch_ftrace_get_regs(fregs) is only valid when the > FL_SAVE_REGS is set, we need to use `&arch_ftrace_regs()->regs` for > ftrace_regs_*() APIs because those APIs are for ftrace_regs, not > complete pt_regs. >
