Subject: reboot: move reboot_notifier_list to kernel/reboot.c
X-Git-Tag: v6.13-rc1~89^2~52
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f2fa0fd4e7db8326a77618962714924b64f5f889;p=thirdparty%2Fkernel%2Flinux.git

reboot: move reboot_notifier_list to kernel/reboot.c

All the functions related to the reboot notifier list are in
kernel/reboot.c.  Move the list itself, too.  As there are no direct users
anymore, make the declaration static.
