Hello, Mike.

The thing is that percpu-refcnting is already in mostly ready-form, so
unless this dm series is planned to be merged for v3.10-rc1, I don't
see the need for a separate near term solution.  Mikulas can just do
the normal refcnting and cgroup will most likely adopt per-cpu ref
anyway once percpu-refcnting is in, so it should all fall in places
pretty quickly.  For devel / testing / whatever, Mikulas can surely
turn off cgroup, right?

Thanks.
