[Devel] [PATCH 0/3] Consolidate cgroup files creation for resource counters (v2)

[Pavel Emelyanov]

Changes from previous version
* made the names configurable
* fixed race between res_counter_populate and reading
  any of these files (memset to zero could spoof the
  pointers)

Right now we have only one controller in -mm tree - the memory
one - and it initializes all its files manually. After I developed
the kernel memory one it turned out, that the names of resource
counter specific files has changed. In the future, if anything in
the resource counters change, we'll have to rewrite all the
controllers we will have by that time.

To make all the containers working with the resource counters
look similar I propose to create the resource counters specific
files in one place.
