That plus the obvious bit. For the pid namespace we have to declare
war on people storing a pid_t values. Either converting them to
struct pid * or removing them entirely. Doing the kernel_thread to
kthread conversion removes them entirely.
we've started that war, won a few battles but some drivers need more work
that a simple replace. If we could give some priorities, it would help to
focus on the most important ones. check out the list bellow.
Sure, I think I can help.
There are a couple of test I can think of that should help.
1) Is the pid value stored. If not a pid namespace won't affect
it's normal operation.
I've extracted this list from a table which includes a pid cache column.
this pid cache column is not complete yet. I'd be nice if we could use a
wiki to maintain this table, the existing openvz or vserver wiki ?
feel free to use http://wiki.openvz.org
we will create a 'Developement' category then for such pages.
I think we can help with the patches soon as well.

I do agree from what I have seen, that changing idioms to the kthread way of
doing things isn't simply a matter of substitute and replace which is
unfortunate. Although the biggest hurdle seems to be to teach kernel threads
to communicate with something besides signals. Which is a general help anyway.
Unfortunately I'm distracted at the moment so I haven't gone through the entire
list but I hope this helps.
If we have some list on the wiki, people could assign the issues to themself and
prepare the patches. Thus work could be paralleled a bit.
Thanks,
Kirill
