#     Pull Landlock LSM from James Morris:
#      "Add Landlock, a new LSM from Mickaël Salaün.
#     
#       Briefly, Landlock provides for unprivileged application sandboxing.
#     
#       From Mickaël's cover letter:
#         "The goal of Landlock is to enable to restrict ambient rights (e.g.
#          global filesystem access) for a set of processes. Because Landlock
#          is a stackable LSM [1], it makes possible to create safe security
#          sandboxes as new security layers in addition to the existing
#          system-wide access-controls. This kind of sandbox is expected to
#          help mitigate the security impact of bugs or unexpected/malicious
#          behaviors in user-space applications. Landlock empowers any
#          process, including unprivileged ones, to securely restrict
#          themselves.
#     
#          Landlock is inspired by seccomp-bpf but instead of filtering
#          syscalls and their raw arguments, a Landlock rule can restrict the
#          use of kernel objects like file hierarchies, according to the
#          kernel semantic. Landlock also takes inspiration from other OS
#          sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD
#          Pledge/Unveil.
#     
#          In this current form, Landlock misses some access-control features.
#          This enables to minimize this patch series and ease review. This
#          series still addresses multiple use cases, especially with the
#          combined use of seccomp-bpf: applications with built-in sandboxing,
#          init systems, security sandbox tools and security-oriented APIs [2]"
