  1571. This kernel feature is useful for number crunching applications
  1572. that may need to compute untrusted bytecode during their
  1573. execution. By using pipes or other transports made available to
  1574. the process as file descriptors supporting the read/write
  1575. syscalls, it's possible to isolate those applications in
  1576. their own address space using seccomp. Once seccomp is
  1577. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1578. and the task is only allowed to execute a few safe syscalls
  1579. defined by each seccomp mode.

  1622. The Extended Industry Standard Architecture (EISA) bus was

  1625. bus while maintaining backward compatibility with cards made for

  1627. 1995 when it was made obsolete by the PCI bus.
