SRU of LXCFS 2.0.1 (upstream bugfix release)

[Stéphane Graber]

LXCFS upstream released LXC 2.0.1 as a bugfix release with following changelog:
 - Fix cpuinfo on s390x.
 - Use recursive cgroup values in diskstats.
 - Allow traversal (rx) to controller directories.
 - Fix do_mount_cgroups() crash on failure.
 - Better error handling in a number of path processing functions.
 - Better error handling in swap calculation.

Just like Ubuntu itself, upstream releases long term support releases, as is 2.0 and then periodic point releases including all the accumulated bugfixes.

Only the latest upstream release gets full support from the upstream developers, everyone else is expected to first update to it before receiving any kind of support.

This bugfix release has already been uploaded to Yakkety and automatically backported in the upstream PPAs for all Ubuntu releases. So far without any reported regression.

This should qualify under the minor upstream bugfix release allowance of the SRU policy, letting us SRU this without paperwork for every single change included in this upstream release.

Once the SRU hits -updates, we will be backporting this to trusty-backports as well, making sure we have the same version everywhere.

I've been running this in production over the past few days without seeing any problem (running a bit under 12000 containers).
