[RFC workqueue/driver-core PATCH 0/5] Add NUMA aware async_schedule calls

[Alexander Duyck]

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
