Commit https://github.com/docker/docker/commit/955c1f881ac94af19c99f0f7d5635e6a574789f2 (v17.12.0) replaced detection of support for multiple lowerdirs (as required by overlay2) to not depend on the kernel version. The `overlay2.override_kernel_check` was still used to print a warning that older kernel versions may not have full support. After this, https://github.com/docker/docker/commit/e226aea280efdc18f887e853b5eefd763b602937 (v20.10, but backported to v19.03.7) removed uses of the option altogether.
