It is to be expected that there will be conflicts when making large-scale changes like this while there is 25MB of unmerged diff sitting out in 50 different trees. Doing it around the -rc1 time would be better.
Even better would be not doing it at all: add the necessary stuff into the block core and then send the followup work to the relevant maintainers. ie: standard practice.

Andi's tree is very out of date and is about to be damaged (to what extent I don't yet know) by a xen merge. I don't know if a) is going to happen.
