Subject: mksysmap: update comment about __crc_*
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c13461693ea21d787f82232ce3a5667da370d973;p=linux.git

mksysmap: update comment about __crc_*

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.
