Hi Adrian,
While testing 'perf top -U' to reply a message in another thread
I noticed that ksm symbols appeared as '[kernel]', and only when I tried
'perf top -U -v' to look at the DSO long name I noticed that it was...
/proc/kcore.
Question is: since we have access to /proc/modules, can't we
parse that, as when we have access to vmlinux, and recreate the mmaps,
etc, and see:
[module] symbol
Instead of grouping everything into a single [kernel] bucket?

I would suggest just splitting the maps and giving them names, rather than
splitting the dso as well. That would mean changing places that have:
map->dso->short_name
to
map->name ? map->name : map->dso->short_name
