Subject: cleanup vfio iommu_group creation v2
Date: Tue, 24 Aug 2021 16:46:35 +0200	[thread overview]
Message-ID: <20210824144649.1488190-1-hch@lst.de> (raw)

Hi Alex,

this series cleans up how iommu group are created in VFIO as well as
various other lose ends around that.  It sits on top of the

    "Provide core infrastructure for managing open/release"

series from Jason.

Changes since v1:
 - only taint if a noiommu group was successfully created
