+       help
+         This kernel feature is useful for number crunching applications
+         that may need to compute untrusted bytecode during their
+         execution. By using pipes or other transports made available to
+         the process as file descriptors supporting the read/write
+         syscalls, it's possible to isolate those applications in
+         their own address space using seccomp. Once seccomp is
+         enabled via /proc/<pid>/seccomp, it cannot be disabled
+         and the task is only allowed to execute a few safe syscalls
+         defined by each seccomp mode.
+
+         If unsure, say Y. Only embedded should say N here.
