+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.
