I think the API patches are ready for serious review. The API patches are the first 3 of 5 that I will be sending. The last 2 concern the refactoring of the "dm snapshot: shared exception store" patches. I left these in a somewhat rough state, and they will need more work. However, I hope it shows that we can create a clean exception store API and adhere to it - even with the more exotic exception stores. brassow -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
