Pull failfs filesystem from Christian Brauner:
 "Add failfs and expose a FD_FAILFS_ROOT sentinel.

  This allows userspace to shed their filesystem state completely. A
  process with its root or working directory in failfs must anchor every
  path lookup at an explicit file descriptor. Absolute paths, absolute
  symlinks and AT_FDCWD-relative lookups simply fail.

  Failfs is the counterpart to nullfs. nullfs says adds a permanently
  empty, immutable directory whose lookups fail with ENOENT but which
  can be opened, read, stat'd and mounted upon. Failfs on the other hand
  fails every operation. The root cannot be opened at all. A single
  instance is mounted during early boot via kern_mount(), which makes it
  logically distinct from every mount namespace.

  This is accompanied by a new fchroot() system call which makes
  chrooting via a file descriptor a first class concept. It's possible
  to chroot into failfs as an unprivileged user provided the task has no
  new privileges set"
