Andrew Morton suggested to move kprobes from kernel hacking menu, since kernel hacking menu is in-appropriate for the Kprobes. This patch moves Kprobes and Oprofile under instrumentation menu. (akpm: it's not a natural fit, but things like djprobes and the s390 guys' statistics library need a home) Signed-of-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Cc: Philippe Elie <phil.el@wanadoo.fr> Cc: John Levon <levon@movementarian.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
