Merge tag 'cgroup-for-5.19-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fix from Tejun Heo:
"Fix an old and subtle bug in the migration path.
css_sets are used to track tasks and migrations are tasks moving from
a group of css_sets to another group of css_sets. The migration path
pins all source and destination css_sets in the prep stage.
Unfortunately, it was overloading the same list_head entry to track
sources and destinations, which got confused for migrations which are
partially identity leading to use-after-frees.
Fixed by using dedicated list_heads for tracking sources and
destinations"
