5Description:	/sys/kernel/iommu_groups/ contains a number of sub-
6		directories, each representing an IOMMU group.  The
7		name of the sub-directory matches the iommu_group_id()
8		for the group, which is an integer value.  Within each
9		subdirectory is another directory named "devices" with
10		links to the sysfs devices contained in this group.
11		The group directory also optionally contains a "name"
12		file if the IOMMU driver has chosen to register a more
13		common name for the group.
