Al, Jan Kara and I have reviewed your patch, and we can add a Tested-by: from David Watson (assuming David, you don't mind your name or e-mail address showing up in the Kernel commit logs --- if you want us to suppress one or both, please let us know). Given this is a 2.6.28 regression, and this can certainly affect real-life users, I think we should push your patch to Linus for 2.6.30. Do you agree? Regards, - Ted
