From a2833d1b07ab107db71a18e6f3855f6908886361 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 26 Sep 2022 18:02:27 +0900 Subject: [PATCH] kallsyms: drop duplicated ignore patterns from kallsyms.c Now that kallsyms.c parses the output from mksysmap, some symbols have already been dropped. Move comments to scripts/mksysmap. Also, make the grep command readable.
