Could some of you test this? It seems to cure things in my (very)
limited testing.
I ran few cycles of cpu hot(un)plug tests. In most cases it works except one
where I ran into rcu stall:
[ 173.493453] INFO: rcu_sched detected stalls on CPUs/tasks:
[ 173.493473] 8-...: (2 GPs behind) idle=006/140000000000000/0 softirq=0/0 fqs=2996
[ 173.493476] (detected by 0, t=6002 jiffies, g=885, c=884, q=6350)
Right, I actually saw that too, but I don't think that would be related
to my patch. I'll see if I can dig into this though, ought to get fixed
regardless.
Thanks for testing!
