  memcg can be handled by memcg people and I can handle cgroup_freezer
  and others with help from the authors.  The problematic one is
  blkio.  If anyone is interested in working on blkio, please be my
  guest.  Vivek?  Glauber?

if Serge is not planning to do it already, I can take a look in device_cgroup.

That's fine with me, thanks.

also, heard about the desire of having a device namespace instead with
support for translation ("sda" -> "sdf"). If anyone see immediate use for
this please let me know.

Before going down this road, I'd like to discuss this with at least you,
me, and Eric Biederman (cc:d) as to how it relates to a device namespace.

thanks,
