[dm-devel] [PATCH 00/18] Clusterized exception store preparation

[Mike Snitzer]

This patch series provides Jon Brassow's refactored DM exceptions,
exception tables and more.  These patches form the basis upon which
Jon's clusterized exception store is built.

Given the fundamental nature of these changes, relative to code movement
and abstractions, the snapshot-merge patches must follow these patches
(particularly because of the way the hadnover snapshot exception table
handover mechanism changes relative to these patches).
