cgroup: rstat: use same convention to assign cgroup_base_stat
In function cgroup_base_stat_flush(), we update cgroup_base_stat by getting rstatc->bstat and adjust delta to related fields. There are two convention to assign cgroup_base_stat in this function: * rstat2 = rstat1 * rstat2.cputime = rstat1.cputime The second convention may make audience think just field "cputime" is updated, while cputime is the only field in cgroup_base_stat. Let's use the same convention to eliminate this confusion. Signed-off-by: Wei Yang <richard.weiyang@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
