Subject: iommu/amd: Flushing and locking fixes
Date: Tue, 10 Sep 2019 19:49:20 +0200
Message-ID: <1568137765-20278-1-git-send-email-sironi@amazon.de> (raw)

This patch series introduce patches to take the domain lock whenever we call
functions that end up calling __domain_flush_pages.  Holding the domain lock is
necessary since __domain_flush_pages traverses the device list, which is
protected by the domain lock.

The first patch in the series adds a completion right after an IOTLB flush in
attach_device.
