This patch set provides functionality that will help to improve the locality of the async_schedule calls used to provide deferred initialization.
This patch set originally started out with me focused on just the one call to async_schedule_domain in the nvdimm tree that was being used to defer the device_add call however after doing some digging I realized the scope of this was much broader than I had originally planned. As such I went through and reworked the underlying infrastructure down to replacing the queue_work call itself with a function of my own and opted to try and provide a NUMA aware solution that would work for a broader audience.
I am submitting this an RFC to figure out just how far off I am from where I need to be on this patch set and to determine which tree I should ultimately be submitting this to.

Alexander Duyck (5): workqueue: Provide queue_work_near to queue work near a given NUMA node async: Add support for queueing on specific NUMA node driver core: Probe devices asynchronously instead of the driver driver core: Use new async_schedule_dev command nvdimm: Schedule device registration on node local to the device
