Subject Re: [PATCH 2.0.5 futex] Fix to Children stuck on futex problem
Date Wed, 07 Mar 2012 03:19:40 GMT
I've looked through those tests, and none seem to apply and I'm not sure
how one would even go about writing a unit test for this.  We haven't
even been able to reproduce the problem on all systems.

I suspect the best we can do may simply be manual load tests (such as
Max and I have done) showing that this patch works.

If someone have a good strategy for how to approach this, I'd love to
see it since I'd much prefer to have a test. I just don't know how here.
