[PATCH 3/3] kallsyms: add more original symbol type/name in comment lines

From: Masahiro Yamada
Date: Sat Jul 20 2024 - 06:31:22 EST


Commit bea5b7450474 ("kallsyms: expand symbol name into comment for
debugging") added the uncompressed type/name in the comment lines of
kallsyms_offsets.

It would be useful to do the same for kallsyms_names and
kallsyms_seqs_of_names.
