Hi Christoph,

I was able to finish the greater part of the necessary work today.
You can find it there:

git://git.drbd.org/linux-2.6-drbd.git flush-fua

Of course that is based on

git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git flush-fua

REQ_HARDBARRIER is not yet completely eliminated from drbd, but I
am very confident that I will be able to finish that by tomorrow.

Best,
 Phil
