It will conflict as well with my shrinking patches: I will still keep
the memcgs in the dangling list, but that will have nothing to do with
debugging. So I will split that patch in a list management part, which
will be used, and a debugging part (with the file + the debugging
information).

I will be happy to rebase it ontop of your series.

Don't worry about it. If this is just this one patch conflicting, I
would avise Andrew to remove it, and I will provide another (maybe two,
already splitted up) version.
