    samples: add an example of seccomp user trap · fec7b669
    Tycho Andersen authored
    The idea here is just to give a demonstration of how one could safely use
    the SECCOMP_RET_USER_NOTIF feature to do mount policies. This particular
    policy is (as noted in the comment) not very interesting, but it serves to
    illustrate how one might apply a policy dodging the various TOCTOU issues.
