Hi all,
I hit this WARN_ON in 3.8 kernel and dev branch. The WARN_ON is hard to
be triggerred because I run test case 8 times to hit it. Here is the
messages from dmesg.
*One Big Note*
Although we get the warning message, the test can pass.

I think I see what's happening. This should be harmless since page likely
has PageDirty set as well and it won't be invalidated. But it's good to fix
the warning anyway. I'll send a patch in a while.
