[PATCH] rcu: fix hotplug-cpu ->donelist leak
Pointed out by Srivatsa Vaddagiri <vatsa@in.ibm.com>. rcu_do_batch() stops after processing maxbatch callbacks on ->donelist leaving rcu_tasklet in TASKLET_STATE_SCHED state. If CPU_DEAD event happens remaining ->donelist entries are lost, rcu_offline_cpu() kills this tasklet. With this patch ->donelist migrates along with ->curlist and ->nxtlist to the current cpu. Compile tested. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: Paul E.
