Subject: [PATCH 1/5] mksysmap: update comment about __crc_*
Date: Mon, 26 Sep 2022 18:02:25 +0900 [thread overview]
Message-ID: <20220926090229.643134-1-masahiroy@kernel.org> (raw)
Since commit 7b4537199a4a ("kbuild: link symbol CRCs at final link,
removing CONFIG_MODULE_REL_CRCS"), __crc_* symbols never become
absolute.
Keep ignoring __crc_*, but update the comment.
