The package says:

This is not true, Kubernetes now imports
github.com/opencontainers/selinux/go-selinux and it has proper
multiplatform support (i.e. NOOP on non-Linux platforms).
Removing the whole package and calling go-selinux directly.
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.
This patch moves the HostUtil functionality from the util/mount package
to the volume/util/hostutil package.
All `*NewHostUtil*` calls are changed to return concrete types instead
of interfaces.
All callers are changed to use the `*NewHostUtil*` methods instead of
directly instantiating the concrete types.
