Subject: kbuild: Ignore __this_module in gen_autoksyms.sh
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ff139766764675b9df12bcbc8928a02149b7ba95;p=linux.git

kbuild: Ignore __this_module in gen_autoksyms.sh

Module object files can contain an undefined reference to __this_module,
which isn't resolved until we link the final .ko. The kernel doesn't
export this symbol, so ignore it in gen_autoksyms.sh.
