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. v2: Dropped nvdimm patch to submit later. It relies on code in libnvdimm development tree. Simplified queue_work_near to just convert node into a CPU. Split up drivers core and PM core patches. --- 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: Attach devices on CPU local to device node PM core: Use new async_schedule_dev command drivers/base/bus.c | 23 ++------------ drivers/base/dd.c | 44 +++++++++++++++++++++++++++ drivers/base/power/main.c | 12 ++++--- include/linux/async.h | 36 ++++++++++++++++++++-- include/linux/workqueue.h | 2 + kernel/async.c | 47 ++++++++++++++--------------- kernel/workqueue.c | 73 +++++++++++++++++++++++++++++++++++++++++++++ 7 files changed, 182 insertions(+), 55 deletions(-) --
