This series consists of a refactoring/correctness of updating the metadata
of tail pages, a couple of fixups for the refcounting part and a fixup for
the stack_start() function.
From this series on, instead of counting the stacks, we count the outstanding
nr_base_pages each stack has, which gives us a much better memory overview.
The other fixup is for the migration part.
A more detailed explanation can be found in the changelog of the respective
patches.
I think this also should be merged into 6.9-rc1 asap, it is easy to
occur when migration.
