The patch titled
Subject: init/version.c: remove Version_<LINUX_VERSION_CODE> symbol
has been removed from the -mm tree. Its filename was
init-versionc-remove-version_linux_version_code-symbol.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Masahiro Yamada <masahiroy@xxxxxxxxxx>
Subject: init/version.c: remove Version_<LINUX_VERSION_CODE> symbol
This code hunk creates a Version_<LINUX_VERSION_CODE> symbol if
CONFIG_KALLSYMS is disabled. For example, building the kernel v5.10 for
allnoconfig creates the following symbol:
$ nm vmlinux | grep Version_
c116b028 B Version_330240
There is no in-tree user of this symbol.
Commit 197dcffc8ba0 ("init/version.c: define version_string only if
CONFIG_KALLSYMS is not defined") mentions that Version_* is only used
with ksymoops.
However, a commit in the pre-git era [1] had added the statement,
"ksymoops is useless on 2.6. Please use the Oops in its original format".
That statement existed until commit 4eb9241127a0 ("Documentation:
admin-guide: update bug-hunting.rst") finally removed the stale
ksymoops information.
This symbol is no longer needed.
