Hi Alasdair, This patch-set is the updated version of request-based dm-multipath. The changes from the previous version (*) are to follow up the change of the interface to export lld's busy state (PATCH 5). (*) http://lkml.org/lkml/2008/9/12/100 All necessary interfaces to support request stacking drivers are now in the for-2.6.28 branch of the Jens' linux-2.6-block git repository. This patch-set depends on those interfaces.
