[PATCH v7 0/2] tracing: Add an option to show symbols in _text+offset for function profiler
Posted by Masami Hiramatsu (Google) 1 month, 1 week ago
Hi,

This series implements an option to show symbols in _text+OFFSET
format instead of symbol name in the function profiler.
This is the 7th version, the previous one is here;

https://lore.kernel.org/all/176179500583.960652.5730113001091388258.stgit@devnote2/

This version is rebased on top of v6.19-rc3 and introduces wrapper
functions of seq_print_ip_sym() for showing offset or not.

Thank you,

Hi Steve,

I've pushed these 2 patches (with Link tag) into:

https://git.kernel.org/pub/scm/linux/kernel/git/mhiramat/linux.git/log/?h=topic/func-profiler-offset

So feel free to merge that branch.
Also, let me send a wprobe patch for this change.

Thank you,
