cgroup/cpuset: Inherit parent's load balance state in v2
[ Upstream commit c8c926200c55454101f072a4b16c9ff5b8c9e56f ]
Since commit f28e22441f35 ("cgroup/cpuset: Add a new isolated
cpus.partition type"), the CS_SCHED_LOAD_BALANCE bit of a v2 cpuset
can be on or off. The child cpusets of a partition root must have the
same setting as its parent or it may screw up the rebuilding of sched
domains. Fix this problem by making sure the a child v2 cpuset will
follows its parent cpuset load balance state unless the child cpuset
is a new partition root itself.
Fixes: f28e22441f35 ("cgroup/cpuset: Add a new isolated cpus.partition type")
