5	Description:	/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.
