Bug Description

I have a docker setup using overlay as its storage driver. I mount an overlay in the container. Both the lower, upper and work directories are themselves on an overlay filesystem. This mount started to fail after upgrading to kernel 4.4.0-38 from 4.4.0-34 with the error message "overlayfs: filesystem on '/mnt/overlay/upper' not supported as upperdir".

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4 stable kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Yes, exists in 4.4.23-040423-generic as well.

Hmm, looking at the kernel source this seems intentional. See commit 76bc8e2843b66f8205026365966b49ec6da39ae7.

Any workaround found so far? (still affect kernel 4.9 [both host and guest])

I switched to devicemapper as the storage driver.
