I couldn't say, I know very little of that, TBH. but I'd say if it was
working before you shouldn't need to adjust anything, b/c my changes in
the arbiter added new functionality, not breaking changes on components
already working. At the end of the day what is did is only allowing
region files to be mapped with mmap() and vm_map().
Anyway, I cleaned up the branches, you can test it yourself:
