The series is in a topic branch and I'll move it to misc-next after one more round of fstests, yesterday's testing was ok. Some of the changes are scary but I haven't seen anything obvious and once it's in misc-next it'll get more exposure so we'll be able to fix the remaining bugs. Please send any fixups either as separate patches or let me know where to do some simple tweaks. Thanks.
