Yeah, from what I've read this is something only related to clang building the kernel with DWARF5, right? I just delayed to tomorrow releasing pahole 1.20 as its late here and there is this discussion going on, what I have is at: https://git.kernel.org/pub/scm/devel/pahole/pahole.git/log/?h=tmp.1.20 There is one patch more than what I think Sedat tried, that makes a Mark's patch for DWARF_TAG_call_site{_parameter} to be applied as well when processing inline expansions, which for what is being discussed here seems unrelated, just avoids tons of warnings when processing vmlinux with gcc 11 in fedora rawhide. - Arnaldo
