Only once, before the fixes, did I ever see an unexplained EINVAL
(from cp), like Andy reports: I'm very hopeful his case is fixed too.

Yes I have reverted my fix and applied all four of these patches (above).
I have just completed a 100 iteration run of my test case without failure.
This would typically fail in the first iteration 90% of the time and
never survived more than two iterations.

I am comfortable saying they resolve my issue.

Are we likely to see these fixes in a 3.2-rcN or will they be going to
stable?
All patches will go to 3.2-rcN and the later 2 patches would go to
stable too, I think.

Yongqiang.

Sounds good, its lasted 24hrs now for me so I think it's safe to stop it. Thx!
