</div>First of all, I'd appreciate if someone from Google kernel people support this change:<br>
<a href="https://lkml.org/lkml/2014/8/4/570" target="_blank">https://lkml.org/lkml/2014/8/4/570</a> . This thing is known to block _any_ attempt to<br>
restore tasks in user namespaces and it's somehow stuck on the mailing lists :)<br>
<br>
Other than this, right now the list of "what we know" is at <a href="http://criu.org/Userns" target="_blank">http://criu.org/Userns</a><br>
AFAIS all items but #1 are resource-specific, i.e. if applications we c/r don't use e.g.<br>
inotifies, we won't hit the "open_by_handle_at and linkat(AT_EMPTY_PATH)" problem. Thus,<br>
we can work on this list in parallel.<br>
<br>
But in order to do so effectively, it would be great to "materialize" this list :) So<br>
I'd like to have someone (see below) to tune the zdtm test-suite to explicitly list tests<br>
that are known not to work inside user-namespaces, and run the rest inside userns. After<br>
that we can fix the known problems one-by-one.<br>
<br>
Now, why I say "someone" :) I cannot plan Andrey's time, since I'm not his manager. Thus,<br>
I'd like to hear your and Andrew's opinion about who can start looking at the zdtm.<br>
