+Description:
+                When read, this file returns 1 if the interface driver
+                for this interface supports autosuspend.  It also
+                returns 1 if no driver has claimed this interface, as an
+                unclaimed interface will not stop the device from being
+                autosuspended if all other interface drivers are idle.
+                The file returns 0 if autosuspend support has not been
+                added to the driver.

+What:           /sys/kernel/profile
+Date:           September 2008
+Contact:        Dave Hansen <dave@linux.vnet.ibm.com>
+Description:
+                /sys/kernel/profile is the runtime equivalent
+                of the boot-time profile= option.
+
+                You can get the same effect running:
+
+                        echo 2 > /sys/kernel/profile
+
+                as you would by issuing profile=2 on the boot
+                command line.
