Don't use those, they have bugs and have since been reverted.
Links to the patch series that Jens mentions are below. I doubt they
apply cleanly to older kernels. Somebody's probably going to need to
take a crack at backporting them eventually (I could try, even), but
I don't know anybody has yet.
Christoph Hellwig (8):
writeback: fix writeback completion notifications
