    Subject[PATCH 5.9 152/757] selftests/seccomp: Use __NR_mknodat instead of __NR_mknod
    Date
    From: Kees Cook <keescook@chromium.org>

    [ Upstream commit 05b52c6625278cc6ed1245a569167f86a971ff86 ]

    The __NR_mknod syscall doesn't exist on arm64 (only __NR_mknodat).
    Switch to the modern syscall.

    Fixes: ad5682184a81 ("selftests/seccomp: Check for EPOLLHUP for user_notif")
