Subject: [RFC workqueue/driver-core PATCH 4/5] driver core: Use new async_schedule_dev command
Date: Wed, 26 Sep 2018 14:51:55 -0700	[thread overview]
Message-ID: <20180926215155.13512.30900.stgit@localhost.localdomain> (raw)
In-Reply-To: <20180926214433.13512.30289.stgit@localhost.localdomain>

This change makes it so that we use the device specific version of the
async_schedule commands to defer various tasks related to devices. By doing
this we should see a slight improvement in performance as any device that
is sensitive to latency/locality in the setup will now be initializing on
the node closest to the device.
