Hi,

The removal of blk_put_queue() broke DRBD as it was, but it turned out
that we can (and should) use blk_cleanup_queue() instead. That will be
release with drbd-8.0.12, which is scheduled for release tomorrow 
2008-4-24.

Regarding the kernel inclusion. Well yes we still want to go that road,
but we where distracted from that with other tasks.

 (At some point we even hoped that Adrian will be of help in that process
  but that did not worked out as we thought)

We will renew our effort for main line inclusion in the next months somewhen.

-Phil
