Hi all, This patch set fixes some inconsistencies between ExtStorage and the other BlockDev classes and is a first step towards disk template unification without breaking backwards compatibility.
This patch set was about to be submitted just before the stable-2.14 branch was cut, but I have been really busy lately and thus postponed it until now. Sorry for this, hope this can be included in stable-2.14. Thanks a lot, dimara PS: The qa-kvm-tiny target in the external buildbot is broken for some time now (gnt-node add fails due to an ssh key issue I think). This patch set passes the doclint target.
