Subject: sched/autogroup: Fix sysctl move
X-Git-Tag: v6.1-rc5~1126^2

sched/autogroup: Fix sysctl move

Ivan reported /proc/sys/kernel/sched_autogroup_enabled went walk-about
and using the noautogroup command line parameter would result in a
boot error message.

Turns out the sysctl move placed the init function wrong.
