Jan --- this is the old version of your patch, which I had dropped
before sending a push request to Linus.  However, I forgot to reset
the dev branch so it still had the old patch on it, and so it got
picked up in linux-next.  Apologies for the confusion.

I've reset the dev branch on ext4.git, and the new version of your
patch will show up there shortly, as I start reviewing patches for the
next merge window.

Cheers,

					- Ted
