Subject: [PATCH 0/2] multi-threading device shutdown
Date: Wed,  2 May 2018 23:59:29 -0400	[thread overview]
Message-ID: <20180503035931.22439-1-pasha.tatashin@oracle.com> (raw)

Do a faster shutdown by calling dev->*->shutdown(dev) in parallel.
device_shutdown() calls these functions for every single device but
only using one thread.

Since, nothing else is running on the machine by the device_shutdown()
s called, there is no reason not to utilize all the available CPU
resources.
