Works well for me, thanks

Just as note: I think this test was accidently added twice. Once in commit 
b13edf7ff2dd0fef95e981170fa71fa6b60421b0 and one time in 
7d64ef43914a734990e48a80bc60686c8db21946 (just checked linux-next, and Stephen 
added it again). Maybe Andrew Morton's tree is out of sync.
