That's really cool :) thanks a lot!
There's one, quite big, thing I'd like to discuss :) So far the most active community
members are x86 guys, but we already have 3 more arches (arm, aarch64 and ppc64le).
In order not to break non-x86 heavily we've set up travis-ci jobs to constantly check
that criu compiles on non-x64 [1]. Also we have arm box and access to ppc64 VM from
IBM and a set of jenkins jobs [2] that run tests on them.
Would you also at least add the former piece, so that we don't break compilation of your
code. And ideally, we'd like to have the latter thing too.

Erm ... this test is marked with crfail in its .desc file, which means, that
dump MUST fail :)

And this one is marked as 'noauto' which means, that the test is a placeholder
for the functionality we want to support, so it does fail now.
How did you run the tests?
