Subject: Re: [PATCH v4 2/2] tracing: Add an option to show symbols in
_text+offset for function profiler
Hi Masami,
kernel test robot noticed the following build errors:
[auto build test ERROR on trace/for-next]
[also build test ERROR on linus/master v6.18-rc1 next-20251017]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch#_base_tree_information]
