All I can say, I believe the patch is correct.

Only one nit... Afaics, fill_files_note() has no callers without
CORE_DUMP_USE_REGSET, so perhaps you should either move it under
ifdef (to avoid the warning) or modify the !CORE_DUMP_USE_REGSET
code to use NT_FILE as well.


Otherwise I can't comment the patch, I simply do not know what
people do with the coredumps. But Denys certainly knows, he works
with the tools which need this info.

Oleg.
