[dm-devel] [Patch 0 of 12] New exception store API

[Jonathan Brassow]

The following 12 patches introduce the new exception store API.  (Thanks
to agk for doing most of the work to break-up the original large patch.)
These patches introduce the API that satisfies today's exception stores
(i.e. "persistent" and "transient").  I have not expanded the API to
include what is necessary for the "shared" and "clustered" exception
stores yet.  I hope we can get these pushed first.

agk, you broke up my original patch, which I then broke up some more,
tested, and bug fixed.
