It was, on the core-updates-frozen branch. When it is merged to master, the=
n you won=E2=80=99t=20
run the test anymore even on x86_64-linux.

I wasn=E2=80=99t aware that the test failed intermitently. That=E2=80=99s u=
nfortunate. From a quick search=20
online, I=E2=80=99m 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=3D597ccb7bf564f65bb059bfe420224cab0fba46ac[1]

Apparently it doesn=E2=80=99t work when run inside a namespace.

I agree, that would be a separate issue.
