It was, on the core-updates-frozen branch. When it is merged to master, then you won’t 
run the test anymore even on x86_64-linux.

I wasn’t aware that the test failed intermitently. That’s unfortunate. From a quick search 
online, I’m not seeing any report of this problem.

One thing which I did find was this recent change to the ioctl_ns test:

https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?
id=597ccb7bf564f65bb059bfe420224cab0fba46ac[1]

Apparently it doesn’t work when run inside a namespace.

I agree, that would be a separate issue.
