                we want to export, so that userspace can deal with sane
                name/value pairs.
 
+               Userspace must be prepared for the possibility that attributes
+               define overlapping bit ranges. For example:
+                       attr1 = 'config:0-23'
+                       attr2 = 'config:0-7'
+                       attr3 = 'config:12-35'
+
                Example: 'config1:1,6-10,44'
                Defines contents of attribute that occupies bits 1,6-10,44 of
                perf_event_attr::config1.
