Thanks Vineeth. Peter, also the "v6+" series (which were some addons on v6)
detail the individual hotplug changes squashed into this patch:
https://lore.kernel.org/lkml/20200815031908.1015049-9-joel@joelfernandes.org/
https://lore.kernel.org/lkml/20200815031908.1015049-11-joel@joelfernandes.org/

https://lore.kernel.org/lkml/20200815031908.1015049-13-joel@joelfernandes.org/

Agreed we can split the patches for the next series, however for final
upstream merge, I suggest we fix hotplug issues in this patch itself so that
we don't break bisectability.

thanks,
