Subject: Re: [PATCH v5 RESEND 0/5] Make cpuid <-> nodeid mapping persistent

Hello,

This also made workqueue blow up when delayed modding races cpu
offlining.

 http://lkml.kernel.org/g/1454424264.11183.46.camel@gmail.com

I'll work around it from the queueing path but it'd be great if the
mapping can be made stable sooner than later.

Thanks.
