Which is presumably why there's another patch

Originally, the patch https://review.whamcloud.com/#/c/31102 was for debug purpose. But the latest version (set 6) offers the solution.

I only see a debug patch shown; https://review.whamcloud.com/#/c/31102
Is there an actual fix patch in flight?

[nasf (Inactive)]

What I learned from the log is that the life-cycle of the cached statfs seems inaccurate. On some degree, that means the test scripts are not robust enough. So even if the https://review.whamcloud.com/#/c/31158 is helpful for this ticket, I still suggest to land current patch to make the test scripts more robust.

James,
I don't have a good reproducer for this bug so I can't tell if the patch fixes anything.
