It's pretty sneaking overloading ->private to let mddev_delayed_delete know that it has something else to do ... wish I'd thought of it :-) Can you add Cc: stable@xxxxxxxxxx at the bottom. Then I'll pull it and send a pull request to Linus. I think it should go straight in. [If a commit contains "cc: stable@xxxxxxxxxx" then the "stable team" will automatically notice it as soon as Linus pulls it - no need to bother them with extra email.] Thanks.
