net: sched: extend percpu stats helpers
qdisc_bstats_update_cpu() and other helpers were added to support percpu stats for qdisc. We want to add percpu stats for tc action, so this patch add common helpers. qdisc_bstats_update_cpu() is renamed to qdisc_bstats_cpu_update() qdisc_qstats_drop_cpu() is renamed to qdisc_qstats_cpu_drop() Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Alexei Starovoitov <ast@plumgrid.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Acked-by: John Fastabend <john.fastabend@gmail.com> Acked-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.
