Clarification: EBUSY is what you get when trying to use the same
upperdir/workdir with two different *concurent* overlayfs mounts.
The EBUSY case is independent of the inodes index feature.

This is not the case in this test, but rather the case of trying
to reuse the same workdir with different upper dirs on *subsequent*
overlayfs mounts.
