I tested with two versions of gdb (10.2 and 14.2), both have the problem. OTOH, lldb is able to disassemble copy_process from a gcc-compiled .ko file properly. > But even with inlining, I couldn't see the warning about the refcount > with my setup. This also matches my observations. gcc-11 compiled livepatch works fine. Thanks, Song
