Please, put any actual content in your mail *before* huge log spams,
especially absurdly big things like lockdep.  It makes it very hard to
find anything you've written, I very nearly didn't here and it'd be a
lot of effort for me to wade through all that text to find it again to
reply to the mail.

Your patch looks basically fine but should use alloc_flags.
