rcu: Don't keep timekeeping CPU tick running for non-nohz_full= CPUs If a non-nohz_full= CPU is non-idle, it will have a scheduling-clock interrupt, and therefore doesn't need the timekeeping CPU to keep its scheduling-clock interrupt going. This commit therefore ignores the idle state of non-nohz_full CPUs when determining whether or not the timekeeping CPU can safely turn off its scheduling-clock interrupt. Signed-off-by: Paul E.
