[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.
