I have a couple of fixes against
fb-rework-locking-to-fix-lock-ordering-on-takeover.patch:

http://ozlabs.org/~akpm/mmots/broken-out/fb-rework-locking-to-fix-lock-ordering-on-takeover-fix.patch
http://ozlabs.org/~akpm/mmots/broken-out/fb-rework-locking-to-fix-lock-ordering-on-takeover-fix-2.patch

Florian has been busy for a month or two - I've been waiting for him to
