    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
