[Impact]
CONFIG_AUFS_FS needs to be enabled in all kernels backported to Focal to keep compatibility when users upgrade kernels in the series. This kernel in particular did not have this config option enabled when the backport was created.
[Fix]
Enable CONFIG_AUFS_FS and make sure it stays enabled on rebases.
[Test case]
* CONFIG_AUFS_FS and its related configs should be the same as the generic kernel in Focal.
* The testcase ubuntu_aufs_smoke_test.aufs-smoke-test should be successful.
[Regression potential]
This is enabling a config option which was disabled before. Due to being intertwined with overlayfs and shiftfs changes in behavior or regressions could be cause on these two other filesystems.
