I'm not so sure about this. We could gather such details already via Ftrace
(e.g. see load_module()). Personally, I'd prefer to maintain a simple list.

Fair enough. It was just an idea. Simple list is a good start. We
could always add more details if people find it useful.

Indeed we could.

Also we should keep in mind that the default panic() message should
be reasonably short. Only the last lines might be visible on screen.
Serial consoles might be really slow.

Absolutely, I agree. This feature should be entirely optional. In fact, it
is likely only useful while reviewing the data via /proc/vmcore given the
potential amount of data generated, in addition to that seen in
panic_print_sys_info(), when explicitly enabled.


Kind regards,
