These exercise lookup traversal from tmpfs into unionfs, which is useful because, unlike UFS, tmpfs does not allow recursion on its vnode locks by default. unionfs22.sh exercises these lookups with a normal unionfs mount, while unionfs23.sh uses '-o below' for the unionfs mount and reproduces the panic described in PR 298201.
