Merge window is a little later this time, and since it was already in for the previous release, we can make it happen.

But can you please base it on for-3.13/drivers however? That's where I'd like to pull in the driver bits, and if I pull this one, then things get even more tangled since for-3.13/core is holding the blk-mq changes too.

Jens Axboe

I'd like to do the merge with immutable biovecs myself though - there's some tricky bits in there. How will that work?

OK, in that case, yeah it might be easier to just pull it in wholesale.
