1799 This kernel feature is useful for number crunching applications
1800 that may need to compute untrusted bytecode during their
1801 execution. By using pipes or other transports made available to
1802 the process as file descriptors supporting the read/write
1803 syscalls, it's possible to isolate those applications in
1804 their own address space using seccomp. Once seccomp is
1805 enabled via /proc/<pid>/seccomp, it cannot be disabled
1806 and the task is only allowed to execute a few safe syscalls
1807 defined by each seccomp mode.
1809 If unsure, say Y. Only embedded should say N here.
